Is my friend avoiding me? Why?

First of all, obviously, she doesn't want to be with you guys. I'm not judging on who is right or wrong here, but I think you should be the bigger/ better person. Just leave her! Let her roam her little self where she wants to! You gave her a chance, she doesn't want it, simply walk away! She could be avoiding you because there's something that's different and she doesn't want anything to do with you. Hint: leave her. This is what I think you should do. Stop the asking. Stop the caring. UH HELLO! She ignored you! I'd be like 'dang girl! uh no you did not just ignore me' (lol. don't say that literally) and leave her butt! Use manners of course. Still say hi IF SHE says hi first. THATS IT! Don't let her just control you! Your welcome! ^_^ goodluck!
