HELP!! boy trouble!?

If you don't feel it with the guy then do both of you a favor and end it now. Stop wasiting both of your times by delaying the inevitable. If you have talked to him about it and he hasn't made any changes he probably isn't ever going to. Move on to someone that meshes with you better. If your best friend doesn't like you anymore because you dump her brother she wasn't a very good friend afterall. I'm sure she will agree with you on a lot of his faults. Good luck.
