I agree with kml, looks like H was trying to keep you as plan B. As soon as you showed signs of not, he gets mad. And yes, threatening that you will have to pay rent and such is pretty illuminating of where he is.

It is really great your kids are understanding in all of this. Of course, they are following their Mom’s lead.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
