Has anyone known a victim of domestic violence?

So I have a woman that I dated and we remained friends. She had been in a relationship with a man so we had no contact. We started having contact again; I was under impression they broke up. While they may have broken up in some sense, they continue to live together. I didn't know this until we met for lunch yesterday.

She shows up and asks if we can talk in my car before entering the restaurant. I had some suspicion because a few days before she told me she dropped her phone and it "broke."

So she's got a black eye, seriously swollen check, bruises all over her neck, arms, stomach area, back. She got the shite beat out of her and I've never seen a woman like that. She hasn't involved law enforcement because he has a child custody case regarding his child from a previous relationship in the court now and she feels that is her leverage to get out (that he doesn't want LEO involvement). She plans to "move out" this coming weekend. She emailed me this morning that he was violent again last night.

Of course she's seeking some kind of emotional support from me; she's probably depressed and desperately wants to be cared for. I verbally express care, but say it's more important for her to be safe and any way I can help, let me know.

Has anyone ever dealt with anything similar?

And if any man has to lay a hand on a woman, he deserves a beating to the edge of his death and I'd certainly like to round up some of my baws and go talk to this fella.

ETA: Some clarity.
