my buddy is 20 years old, wants to marry this 23 year old girl. problem is, he is the only person out of our whole group that gets along with her. she does not like any of his friends, including me, his best friend, at all. we barely see him anymore, most likely because she does not want to hang out and drink with us. he wants to quit school, and juco football so they can get a house and get married. how can we get it into his head that he is making a mistake? he is dead set on doing this, and we dont want to lose him. we feel at this point that if we confront him about it, he will do it out of spite. what is the best route to take in this situation?
