Anyway they've been dating for about a month, and of course she tells me everything about their sex life. It started out normal, then one day he pulled her hair during sex. We laughed about it and moved on. Then he started biting her, hard...and everywhere, leaving MASSIVE bruises and welts all over her. She said she didn't mind, except it got so bad she couldn't find any clothes to cover them, so she told him he had to stop.

That was fine, time went on a bit. About a week ago though, he started choking her...only for a few seconds at first but when she didn't resist every time they had sex he'd do it longer and harder...until the other night she told me he did it so long she actually blacked out for about 10 seconds. After talking it over for a bit she decided to tell him to ease off a bit. The latest development is he's started spanking her, aswell as the choking and the occasional bite and hair-pulling.

What I'm really scared of it what comes next. He seems to get weirder every week, and if he's slapping her what if it gets worse. What if he takes it out of the bedroom one day and gets abusive in every-day life. She's spent every day this week at his place, and I'm scared they're spending too much time together and he'll do something worse. He's the most jealous guy I know, I just don't want something to happen. How am I meant to bring this up seriously with her, without offending?
