What am I to do about this? I am losing a great friend. And I might leave the friendship.?

My friend got into a relationship not to long ago and he shows all the signs of a controlling boyfriend, and she has mentioned to me before that his dad was really abusive towards him and his mom. I think my friend mistakes the controlling for caring, but he is getting a little too extreme. They swapped one another's FB account info and he reads all of her messages so I can't talk to her from there as I used to anymore, he gets really upset when she tells him that she is going to hang out with me or any other one of her friends, he constantly will be calling to check up on her and accuses her of cheating. To be clear he lives out of state, and she plans to move away from me and other family to be with him, out of state. He is set on her moving in with him, and has told her multiple times that he doesn't like the fact that she is friends with me because I tend to point out the things that she isn't noticing. He doesn't even have a stable job to support her. I notice whenever I am trying to talk with her, make plans, or he finds out that she is with me then he will make her feel bad, guilt her, and get upset. He has given her a curfew as well. She listens to everything he tells her to do, it's a very unhealthy relationship and I am noticing this more and more everyday [there has not been a day where they haven't got into an argument and that he hasn't made her depressed, because he does exactly that everyday.] How do I make her aware without her flipping out and telling her bf?

Damn. Um, I think you have to open her eyes. I think one thing will come to another and he'll end up abusive. Tell her this. Like really, sit her down and tell her about him. He seems kinda weird. Like a little too obsessive with trust issues and such. You said he doesn't like her making plans or w/e, wtf??? She's never gonna have fun. Maybe she will realize this later if you don't tell her now, idk.
