Friend problem?? what should i do?

i actually can relate to you a little! i had a best friend who was exactly like the way your describing your friend. i would advise not to continue hanging out with her=( sorry, but it sounds too familiar to what i kinda went through. my friend never did change her ways. We ALWAYS got into arguments, and basically i was always wrong in her mind. .i tried talking to her about it, but it was like it went through one ear out the other. your only gonna continue to get hurt. But if you do want to continue a friendship with her. try to talk to her about how you feel, and how its affecting you. give her a chance. if you see that she's not changing, give her the boot!
