Definitely, definitely warn your dear Daughter, Envious, not to contact this "man", and I use the term loosely.
I was in a controlling relationship years ago until I saw the light and ended it. I nearly ended up contacting him after he sent me a nasty, abusive letter, to ask him why he had sent it, but Thank Goodness for a wise Friend who was able to see what would have happened had I contacted him, and persuaded me to ignore him. Best advice ever, and I got over that letter realising that what he was doing was trying to reel me back into his web. Yes, it was hard because I ( falsely, I later realised ) blamed myself. Don't let your Daughter fall into that trap, and get her to read these answers. We are all rooting for her. ???.
