If you were a guy people would call you a jerk and that you only used him for sex. I find that a little interesting.
Things like this happens and it's nobodys fault.
Sometime we are in love with an idea of someone rather than the person itself and when we realize that that person isn't this idea or dream we sober up to reality.

Maybe you were only attracted to him in a physical way. You probably don't like his character or his personality, that's why you are feeling confused right now.
Anyway, go on a date with him and you will decide then whether you like him or not.
