Is there any problem in marrying a girl of same age or just2 3 months elder than you That too if she was your classmate?

There is generally no problem in marrying a girl who is the same age or just a few months older, especially if you have a strong, compatible relationship. Many couples find that age differences of such a small margin have little to no impact on their partnership. If both individuals are emotionally mature and share common values, being classmates can even enhance their bond. Ultimately, the success of a marriage relies more on mutual respect, understanding, and communication than on age.
