I saw you posted in someone else's thread recently so i know you're around. I am guessing you're upset with the 2x4s about the house situation. I know it probably came across as very harsh, but with everything you know about DBing, you know that the house situation is pretty bad in your sitch in terms of your W feeling any loss and feel the consequences for her actions.
Just come back and post. If the house situation is truly unsolvable as you have mentioned, what are some things you can do moving forward? I would still push what others have said - can you not move back in and tell her to find a new place and do whatever she's doing with OM?
Have you consulted a L about this? It's your matrimonial home so you must have some rights about it.
Everybody here cares and we want to help you in your sitch. Don't lose hope - not just yet. Come back and talk to us.
