Marriag eis complicated

Ok...wow
A guy I dated a couple of years ago, for this sake let's call him Bob. Got married a year ago I think, and it was a civil marriage to a girl who had a son that was already 2 or 3 I believe. All along I've heard rumors that they've been having problems in their marriage and stuff, but as you know, rumors get exaggerated and so forth, and I didn't pay any attention to it. Well, today Bob messaged me asking if he could talk to me in person, (in a public place of course), and I told him with that I might not be around tonight, but it depended on when a certain person got back to me about work. So he just started going off in the message, saying he thinks he's about to have a divorce with his wife, they've been separated three times thus far, right now is the third time, and they were separated on Thursday. Right before that he got so angry I guess he says he lost control and hit his wife causing a bloody nose and split lip. He doesn't know what to do...so what am I supposed to do? He's begging her for one more chance, and she says that he's given her many chances (I believe that if they've been separated a few times). He's deaf, and he hasn't had a very good life growing up. He lives off of SSI, which if anyone knows anything about it, is not nearly enough to support a family. He doesn't go to school or work. He's contacted a counselor at BYU, but there is no interpreter available since school is out is what the director said at the counselor department. he says he realizes he's selfish and needs to get his butt in gear by getting a job and finishing up school. What am I supposed to say to this?
