My friend kinda invades me LIFE?

well shes not really a friend. i wouldn't want to be friends with someone like that. my best friends i just feel so comfortable around and i know i can always trust them and they would never do anything to me like that. just try to separate yourselves a little. like don't invite her to your house or go out of your way to hang out with her. and when she asks you to hang out make up an excuse. if you do this for a while you'll slowly separate.
