Should I say something or what

So my rommmate in college and I were randomly paired and very similar! We have become very close friends. Well recently the things she has told me about her bf saying things to her seem very controlling. They have only just started dating. If she was any of my other friends I would have had a serious talk with her. I know it's not my place but still she tells me this I feel like she's semi asking my advice. I don't want her to get mad at me but still I don't want her to be like mad at me. But I feel like if I don't say something I will regret it cause maybe I could have helped her. It's mainly him telling her what she can't do but it's very extreme (can't hang out late with friends, can't go out and drink(like I'm talking a glass of wine not like clubbing!!)
