I am engaged but am confused about getting married

My best wishes to you and hope that your upcoming time should be enjoyable with the present alliance. Hope everything goes smoothly when you finally meet your fiancé in the next time. However there are certain pressing issues for which there is no immediate answer from my side so that I can be rest assured for the stability of your marriage.
The following are the points with which I am constantly being bogged down and you alone can provide me some tips in this regard. The questions are as follows-
1) What is the academic qualification of your fiancé? You have asserted that he is living in UK currently but no details have been provided regarding your qualifications and service. Though both the parameters have vital links in augmenting his financial status. So far, I presume that he is capable enough to earn decent income but still, by knowing the details of his source of income and qualification would further make you comfortable.
If still, you are in dark keep yourself updated with this sensitive information. Rather, I would emphasise you to collect all such vital informations before getting your marriage settled.
2) The second point relates to the family members of your fiancé and most importantly the nature of your in-laws and their accompanying reactions towards your acceptance as a marriage partner. You are silent on this issue. Not necessarily, you keep me apprised of the facts but you reassure your self for your comforts.
3) Instead of being guided by his looks, you will do better to know his stability of income, his reliability and his emotional bondings with you. These positive attributes would be enough to settle your marriage finally providing you a blissful life after marriage.

Already engagement is over. You met him three times. You are talking to him daily for an hour or so. This exposure should have given a clear-cut idea about the boy.
I feel your marriage is an arranged marriage only. It is happening with the consent of both families I think.
Never worry about looks. Already you both came out of that stage. Both of you gave consent to each other. Now is not the time to think about looks.
But please talk to get more details about the boy, his job, his friends etc. If possible try to ensure that the information you are getting is correct. Try to know about his nature and other habits and see whether they suit you are not. His profession and earnings are also important for you.
Is he staying alone abroad? Where are his parents staying and what is their family history? Get these details and get satisfied.
Once you are happy with the details, don't think about looks.

If engagement is done then you should be happy. You always think positive about your marriage. You said that you have met three times then you should have all information regarding him for e.g- what is his qualification, how much does he earn, what is his habit, liking/ disliking, what is his future planning etc. As far as the look is concerned, it doesn't have importance in life, especially in the case of a male member if he is doing a good job. As mentioned above, his nature is good then it has more importance in life compared to good looking. Life runs on wisdom, not on look. I think bad-looking boys are more adjusting to married life. So, you should ignore looks. And focus on finance, habit and other important things for happy married life. Always remember that beauty is temporary but good nature is permanent and it gives benefits till the end of life.

Marriage is a life time commitment. It is natural to think various aspects before going for that type of relationship. There is nothing wrong to have a little worry about the future of the relationship but overthinking would not be a correct thing as it might induce stress in the person concerned. You have already got information about the person and have talked to him and as per your observations he appears to be a reasonable person having a good behaviour.
There are many things which are to be understood clearly in these matters. First thing is have you enquired or already know about his family background? This is important because you might have to interact with them and maybe for sometime live with them. What is the boy's plan in that regard? Would he take his parents there or will be alone in UK? Why I am asking these simple questions because tomorrow you should not complain that you were forced to live along with his parents.
Another thing is the job position of the boy and his financial stability. This is a very important point and there should not be any confusion on this account. Suppose the boy has not told you his actual job position and salary and informed something in vague just to satisfy you and later you consider it as cheating. At the same time what is your financial condition? Would you be trying to get a job in UK or live like an ordinary housewife? If the answers to these basic questions is obtained much of your fear and headache would be removed from your mind.
One of the things that often happens in such long distance negotiations is the extra marital affairs. To seek a young company for an adult is a nature's call and there is noting wrong in it but if that is known beforehand then there is no problem otherwise our dreams are often shattered with that information coming to us after entering in the relationship.
On the same lines you should also not hide anything about your past and should not feel guilty about that. In young age many people err and realise it later when the relationship is finished. Do not have any type of inferiority complex and go ahead logically and rationally after getting as much information about the boy as possible. Please note that what you are doing is to shape your future and there is no bad intention of spying a person about his personal matters.
If you intelligently ask your questions and queries then many answers you can get from the mouth of the boy himself. Do not just believe the sweet words that a person talks. All that glitters is not gold. The point I am driving is that there might be some shortcomings in the boy and that is not a big deal as no one is perfect in this world but the thing is that if you know that beforehand then later there is no shock for you. After getting more details one can take a better decision.
Marriage decisions are always difficult to make and the main reason is that we always search a perfect boy or girl without assessing our own shortcomings. If that is well understood then unnecessary worry would not be there.

Let me start with a quote I use in such contexts, that is " present fears are less than horrible imaginations".
I also convey my best wishes to you.
The core of your issue is actually found in your own statement "I am an over thinker. I keep thinking and start getting anxious. Some days I feel normal and some days I am anxious that everything is going wrong." When a problem is diagnosed correctly, the treatment and remedy is easy.
You are not alone in this world who experience such confusion and worry in one or other situations. A prudent and rational person can find the solutions for many problems by oneself. That requires a review and proper analysis of the issue and then remove knots one by one. That will reveal the right solution or remedy.

I would suggest that instead of worrying and having sleepless nights, please earmark just one or two hours a the earliest opportunity leaving aside all your other works.
Take a pen and a sheet(s) of paper. Draw three columns. 1. What are the positive points in him/with this alliance 2. What are the negative points I see in him/ this alliance 3. What are the points where I am confused and need clarification.
Then write or list down one by one points coming to your mind under each category.

At the end take a total view and se whether positives are more or negatives are more. Then se how many confusion points are there.
Next try to find how or what changes will make turn the negative points to positive points. Note down the needed changes there against. Now try to find a positive answer for your confusion points. If still you are not finding positive answers then leave them as such.
Now add the original positives, the amended negatives and amended confused ones to the positives. If these are more then you can go ahead and think of finalising marriage after a little more discussion and interaction with the person and also with your parents and close well wishers.
I presume that your parents are also involved in the decision and engagement. If so it is better to confide and discuss with them about your confusion.

If you have still lack of confidence, then frankly tell your parents and him that you need some more time to interact and feel comfortable and confident and postpone marriage suitably. I se a hint of silver line in your own statement-" Sometimes I feel like I may be comfortable once I meet him next. Maybe my confusion is because we haven't spend much time together yet and it will be okay with him" I wish let such positivity happen so.

If you believe in God and prayer, then do pray to God(in whatever way you practices) along with the practical suggestions I gave above.
Be confident that all will end well.

( If all other factors are positive and n agreement for you, looks need not be given undue weightage if otherwise he is a normal person and there are no offensive unpleasantness i his looks. After all the makeup and grooming is done even to the best looking persons. A happy and healthy life, a peaceful and supportive family etc. can make anybody look shining in face. You can make such a good family if you wish and will)

The most important thing in any relationship to work better is understanding, friendship and respect. These are the top priorities which can make any environment livable and beautiful but lack all these things and having just handsome features, beauty and a beautiful face but not a good behaviour will never work in fruitful ways. As far as looks are considered it is obvious for any person to look for this feature in their partner when this partnership is going to be lifelong and bound by sacred rituals but they are secondary if you like other aspects of the personality in your partner to be.
But the aspect of looks can not be ignored completely if one found another person completely repulsive then it will be very difficult to live in such a relationship as well. So with other things, one has to see that dislike towards someone's facial features and personality should not be to the extent of repulsiveness.
Leaving these things aside as you said you are an overthinker and thinking too much then you should have more conversations with your partner about your other insecurities, fears and future life which will give you a better perspective and clarity on how life is going to be after the marriage and then decide if you find all other aspects in his favour then looks definitely come secondary and are a superficial part of a good relationship.

Let me start with the very blunt and straightforward line -'don't get married if you have even a slightest bit of confusion about this marriage.
Marriage is not something that you can do with the thinking that let's do this and we will figure out everything later on. A big no this. Whether you're confused about his looks that you might not feel attracted to him or you might not fall in love with him, give yourself and that man sometime before getting married. That 'sometime' can be a small time like some months or a long time like a year or so. but, you should give yourself and that man this time so you can start the new beginning from a happy and satisfied space without any confusion about the marriage or that man.
IF you start this relationships with doubts , that relationship is going to suffer and along with it you two are going to suffer too.
So, talk to him about everything, your doubts, your confusions, try to know him and understand him better and let him know you and understand you better. That's where the love starts when you both come to the same page.

If you are confused you should not marry. Simple!

As it is a very important decision of your life, introspect and take the advice of those who you think are most reliable. Your family condition, financial condition, your would-be partner's condition job, caste (if you believe), etc. are to be considered to take a decision.
