Should I take her back as a friend? Long, but I need advice!?

Oddly enough, I've had similar friends. The ones everyone calls crazy and over possessive? Yeah, it doesn't turn out well. What she did was wrong. She was jealous of you, and was happy about making you upset. I don't think you should be good friends with her any more. Maybe add her again on Facebook, but don't IM her or anything. If she talks to you, reply back a little as possible. You should talk (and maybe forgive her), but not become close again. I made that mistake, and it causes a LOT of drama, which you really don't need. Best of luck!!
