What should i do about my boyfriend?

hiya, she is a trouble causer,and she knows what she is doing ,when she talks to your bf.i would not be surprise if she asks your guy to sleep with he as a friend,nothing in it.but just for .i think she is jealous of your bf,and would not turn any offer down,if he was into her.i would keep your guy away from her.and just hope she does not get hold of him,when you are not there. good luck.xx
