You guys are way more patient than I am. When mine dropped the bomb, she stayed in the house for a month after and we were on the roller coaster too but I could not take it and actually asker her to please move out ASAP. We were getting nowhere and the way she was treating the kids (ignoring) was killing me and her. It may not have been the right thing to do but I think it was better for my kids than to try to understand why their mom went from doting over them to ignoring them.
It is a tough spot to be in guys. I wish all of you and your families success.
