At those ages its tough. I have a friend who secretly started dating his wife when she was in junior high while he was in high school. Once she was 18 they officially started dating for a year then did the one year engagement and then got married to be all proper but they had known each other for like half a decade or more before the official thing. Have not hung around with them for awhile but from facebook they still seem to be married and their kids are getting pretty old. Ultimately he is only like 4 years older than her and something which if your talking 18 and 22 is no big deal but 18 and 14 gets real weird.
