i) a man has to be the leader of the family, the fact that she is so much older and knowledgeable than you, can she accept that she has to listen to your say?

ii) have you evaluated what is the reason that you fell in love with her and do you know what is her reason to falling in love with you?

iii) this thread belongs to cupid corner and not "bride and wedding" forum!

Honestly, there shouldn't be a problem as long as she doesn't find him to be too immature.
