A wrong story has been portrayed by you. The story is not for marriage. It was Narada who created problem to Ganapathy and Subramanya. Narada brought a special mango that cannot be shared. He presented to Shiva for its divine power. Shiva wanted his sons to have the power, but cannot be given to both, but to only one. Shiva thought of a competition as suggested by Narada. Whoever goes around the world first, will be given the fruit. Lord Subramanya took his peacock vehicle and took off to come around the world. Vinayaka with his big tummy was blinking as he cannot go around the world on his little mouse. Narada gave an indication through his body language to come around his parents who represent the world. Ganesh understood and he took three rounds of his parents Shiva and Parvathi, and said," My dear Dad and Mom, you are the world for me. I came around you three times. Please give me the holy fruit. " Shiva and Parvathi were pleased by the action of Vinayaka and presented the mango to Ganapathy. When Subramanya returned, he found the mango in the hands of Ganapathy. He got annoyed and left kailash to settle down in Pazhani hills with his one feet Langod after a tonsure. He is known as 'Kovanandi'. This is what the story. There is no connection between this story and Ganapathy's marriage.
@ Mr. Partha:
Lord Subramanya is not a bachelor but a husband with two beautiful wives. He is married to Deivayanai, the daughter of Lord Indira, and Valli a Gypsy girl. Lord Ganesh is still a bachelor looking for a suitable bride who should look like his mother Parvathi. As per the Tamils, Vinayaka is still a bachelor Lord.
Chronic bachelor means - A bachelor forever. (Though Chronic refers to a bad thing or a problem, I feel, remaining as a bachelor is a bad thing in life when God has created the opposite sex to marry and enjoy life. Remaining as a bachelor can be a disease also. Hence, it is said as Chronic bachelor)
