Strange, Bro, I just checked in on you, Sorry things went from bad to worse, I know the feeling all to well, I just want to lend you my support, and say that it sounds like Nomo is right on with everything he has said, I Thank God we didn't own our house, that would be a total nightmare. I know that you are a strong person and I know that you will do the right thing.
I don't think that WAS's really don't understand the all the ramifications of when they drag their personal problems into the legal system, Course if they had any sense they wouldn't do it, but you know them, they are always so sure and headstrong. Just wait till that bubble bursts and a cold dose of reality hits them right smack dab in the face, it comes in more ways than one, it might come financially, emotionally, or physically, but believe me it will come.
Take good care of yourself, and Hey, if it comes to it, Mom's or as you might say Mum's LOL, couch is better than the cold street, right? Make the best of your sitch, and you can't go wrong, I know that you have, and I know that you will continue to do so. Peace to you on this journey. Take care.
