Your H has a curious way of sweet-talking you to win you back.
Sorry you're going thru this.
Stuck, the only thing I'd add to what you said is not to make comments about finding a real man. He's shown a predisposition to jealousy and violence, there's no point in making an inflammatory comment like that, especially when she's not looking for another man.
Her H would glom onto a statement like that and claim there was someone else or something crazy like that. Anything but take responsibility.
