I think you should talk to your sisters friends (if you know them) and then agree that you should all try your best to convince her to leave him, but make sure you don't alienate her in the process (women in her position can be very irrational and may actually feel that everyone is against her and her BF)

Especially if he has actually physical hit her, I can't see them not agreeing.



You should sit down with your sister and talk this over. She must understand that whatever she is feeling, it isn't worth this, that there are many nice men, much better men than this guy out there for her and that she is wasting her chance at happiness and the right guy by sticking around (I know, its silly but appeals to the emotions often work better than logic in such situations).


Then tell her that the only reason she is sticking around is the same reason abused wives stick around their husbands they subconsciously think they don't deserve better/they think they can change the husband (pick the one you think will work better) neither of which is even remotely plausible.
