I have to get one of this mess?

wow she seems like a mean drama queen...if i were you i would act the same way she does to you but to her, try not talking to her and do not apologize let her come to you first and if you dont like that option just go up to her the next time she treats you badly and say " look i really dont like the way your treating me...do i ever treat you like this...no i dont because friends dont act like this to each other" and then sorta put in there how you want a break and about the secrets thing if you guys are really good friends she probs wont tell but make her feel really bad cuz if she actually cares about you then she will understand....i hope this helped.
