Does anyone understand guys?

Well, he answered himself. He didn't want commitment; seems to me, you were the his sex partner. Guys do that---they go out with a girl for the sex, and then they break it up because they found another partner; granted, you can say, "but we dated for 3 years"---i know guys that have done that for 5 years, and as they call it, best to have some safe p**** than no p****. By the way the fact that he said that clubs sucked, yet he went there with another girl, only confirms my conclusion that the only reason he didn't want to go there with you, was because that's where he probably got his other hoes, and didn't want to be seen there with you. Standard excuse.

I don't know how old he is but it seems to me that he didn't really have a chance to run around enough before you get together. He is behaving very immature and I am sure you will soon meet someone who would be ready to commit.
ignoring him and concentrating on your own life is the best way to go.

I have to agree with sexwiseman again! He did not want a commitment with you. He is having fun, he just did not have the nerve to tell you the truth. Which, really shows this guys character. You should go out and have fun clubbing yourself. I know you are sad and hurt but, this guy falls under my notorious jerk category.
