somebody plz help me?

I think you need to understand that he is with you!!

You both have friends of the opposite sex I'm sure. In your case it sounds like she may have known him first if that's the case then you need to honestly deal with it. Some will tell you to confront him and I think that's wrong.

Would you want someone telling you they don't want you to be friends with someone when you have known them longer then the person who is telling you they don't like it. Not only is that wrong, its selfish.

We all have our pasts weather it be old friends, maybe old lovers even but they our part of who we are. It maybe different if she was trying to inter-fear with your relationship but from what your writing it sounds like they are just friends and you are having some selfestem issues.

Hes with you and maybe if you stop worring about their relationship and concentrate on his and your relationship you may find you become even closer to him then she is. Don't loose something nice because you are jealous and being selfish.

just tell him the true feeling you have and be happy with it..dont be rude if he doesnt choose you..just be there when he is down and later he will get your attention you wanted to ..he will not yet appreciate you now but when trouble comes be a freind.
