How do I stop living selfishly for myself and learn to love living for others? Girls always want to get married and start families and i know i want that some day and I think its good, but right now I just dont want it. I don't think about it, I don't have fantasies about it, and when I get pressured to take it seriously I just think "sheesh sounds like a lot of accountability and responsibility, no thanks"

My life is really good as an unmarried man, at least right now, but I'm afraid that if I wait too long, no one good will want me and I'll end up alone and childless, but I'm also afraid of commitment and think its wrong to tell a girl "I want to get married and have kids" when its not true, I just don't feel that way right now

Damn this really causes serious internal conflict in me, any advice?
