Wow, i definitely think you have every right to be angry. If my friends did that to me (which i'm sure they wouldn't) I would be clawing the walls. Maybe the upside of this predicament is that now you can see the person that she probably really is. She may have done similar things to others whilst you were her friend, but then you may not have noticed. I hope that you can sort this out, sounds as if you're having multiple problems, and i really do feel for you. If you want to talk, i'm just a pm away
