<human>: We're both sophomores in college and have been dating for about a month and a half but talking since August. I've never felt like this about a girl and I really feel like I could've ended up with her for a very long time. She's perfect for me except for one thing, her social life. She goes out to fraternity parties once, twice, maybe three times a week. She says she has friends in the houses and she has fun with her girl friends and guy friends just chilling but I know these parties and frankly, every time I see a girl there that is dating someone I feel embarrassed for their bf and that's me now. I know she'd never cheat on me but I'm not comfortable with my gf doing that. If this is going to be as serious as I want it to be then everytime she goes out I'm going to constantly be worrying and it's ruined whole weekends of mine. Anyway, I told her today that I can't seriously date someone that drinks regularly without me at places where drunk assholes are just trying to get in her pants. She said that she couldn't promise anything and I decided the best option for me would be to dump her and get over her now before I really really become attached. I just hope I'm making the right call and not ruining the girl I could be happily married to down the road. Your take?
