What an awful thing for someone to say about your M. Its none of his business. You need to be documenting these incidents. Whe your H goes against the verbal agreements and takes your D without telling you where he is going, or when he is bringing her back, HE is not showing very responsible behavior. And especially when he is being verbally abusive! Document, document, document! If at all possible, get witnesses.
Shannon, I am not telling you to try to fight dirty, or to be as down low as your H, I am telling to to protect yourself. By documenting these things you can at least disprove some of what he says, or make his outrageous claims at least a little less credible.
It seems to me that you are dealing with a WAS and MLC. Two for one! As far as Im concerned, even the most "perfect" Ms have issues, and for someone to try to point out flaws in yours, or to tell you that you need to move on, is so wrong. Kind of like pointing out how terrible your M was, it made him feel better about his... Or maybe about the fact that he wasnt M at all!
Let him go down this road alone, it will hurt everyone involoved, him, you, your D, and the OW. You are absolutely right that they are proceeding under duress. They are forbidden right now, and its all new and exciting, once things get really ugly, or once they start to resolve I think that they will fall apart. Does this woman actually not have a problem being represented in court as the OW? If it comes up at all in court, can you refer to her by her full name? Lol. I cant imagine that she will stand for that, or that she wants to be the one being dragged through the mud. Maybe thats what she gets for being a homewrecker!
I guess I gave the wrong finger to the wrong man...
