Also, you seem to put emphasis on the kids being 'girls'.
Nurturing kids is no easy task, without the presence and support of the other partner, be the kids be boys or girls.
You actually have appreciated that woman, it can be seen. It is only that one point, which you make, that is problematic: "How she would have coped up in this world when nurturing teenage girls without husband's physical presence is greatest challenge. "
You are underestimating her as a woman, more than you are appreciating her as a wife and mother.

Even this challenging situation would ease
I always have a healthy respect for parents who almost single handedly look after the family needs and children.
For the sake of money to give their children a better future some parents father or mother (doctors, nursesm construction and oil empoyees) work abroad with little choice. They would miss their families and would lose the golden years of seeing their children grow up.
Equally difficult is the job of the other parent who runs the family back home. He or she has to manage daily affairs, look after their needs, health and social issues. They also have to support families and relatives whenever possible.
Such people sacrifice the joys of marriage life for long years with the true desire to provide more for the family and children. Few do it by choice, most do it by lack of a better choice.
