Yep, it does make sense. I'm doing the 7 daddy days on and then 7 days off. I wouldn't say it's limbo, but for sure like leading two separate lives. Totally get the new place, fresh start with kids AND there's great hope in knowing that will be coming. You just have to keep making it through and you are.
As far as your WW you said it best yourself: I will go about this, with a mindset that says, be cordial, be respectful, be strong, be yourself, and dont let hatred and resentment build a foundation within me. In time everything will be better, and for now and forever, my kids are the most important.
THAT ^^^^ is the ONLY contract you need to make with yourself. Just let her go man. Too much good stuff waiting for you on the other side. Keep going forward for you and your kids. That is all you've got to do.
