How often do you meet a really nice person you really like.

Ok I've been in a relationship for 6 years and we are most likely going to call it quits. What is really bugging it about me is I meet girls in college and see girls around in stores, the mall, bars, clubs and I never met a girl that I would replace my girlfriend with, although I avoid meeting girls because of my status. How often does a nice girl come along I never meet any, I never see a girl and say wow she looks like a nice person! I am very attractive and it just seems too easy the way girls act around me. I love my girlfriend but I am almost positive it is over, story is here:

I really don't want another girl but I am forcing myself to find one, as I am sure she is ready to move on. This is the toughest thing I have ever went through but I am happy I am going through it because the bad times make the good times better. Anyway I am just very worried because I am very picky with girls even though my girlfriend right now is not a knock out, I was never attracted to her very much and I always took her for granted but she was always great to me. I never thought she was pretty it's amazing I was actually embarrassed of her, I mean she not ugly she's like an 8. I'm afraid to date and find out girls are not like my girlfriend and its going to make me depressed!
