i know i am not good enough for him,he is perfect but...?

I think he is playing your low self esteem. He is not perfect he is a perfect jerk. You need to find a nice guy who will treat you well and make you feel good about yourself.

First off don't feel used and worthless. Maybe he is lost in his own way. Sometimes even the perfect person you see has flaws and that's human nature. If you like him and are scared of losing him then you got two options, keep him as a friend and in time the relationship will grow stronger or you could be up front and tell him the truth and have that chance of losing him. Either way you take that risk of losing him. If it were up to me I would say take a slow approach and make him jealous later on.

break up with him. I cant tell if you are together with him or not. DO NOT ASK HIM. he is not interested in you and if you ask him and get rejection that sucks cuse rejection is a *****. This has happend to me before and i got rejected badly and it took me a long time to ever trust anyone again.

No, go with your first instinct that you are not good enough. If he's a normal guy, he probably will not put up with your complete lack of self esteem.

you really need to work on your self confidence. dont think of yourself lower than any stupid boy. what makes you think hes better than you? there is no ranges for anyone. why do you feel used? did you have sex with him?

dude that sucks that you feel so low. what you really need is a friend that could actually be with you to talk it through with them.

tell the guy that you like him if he dosen't like you back than it's ok right? you gave him a try! plus i beleive you are to pretty for him to not like you!
