She sounds like someone you should stop being friends with. Friends don't steal boyfriend or do other immature things to you. She is not a real friend if she does those things. She is not worth the frustrations that I am sure you are are having. I've had bad friends in the past and its easier to just stop being friends with them. I am actually friends again with someone I stopped being friends with in my early high school years - we are both almost done with college now. She grew up, became mature, and is now a good friend. So if your friend does that then you can be her friend again.

It sound like she's not a good friend. If I were you i would forget about her. If she is going to stab you in the back like that then she is not a real friend and is not worth your time or effort!
