Wanted, Just wanted to offer some reassurance to you regarding the move out. I had a fortunate opportunity with th ein laws going on a 40 day cruise. I didn't force but firmly suggested W go stay there while they were away. There were some bumps getting a child minding schedule set up but it settled down and while not ideal for the kids right now it is working. I can tell you that I am now dreading the day the in laws return and W has to come back home. It is all what you make it but life by yourself is not bad, actually I would say it is better. It gives you the freedom to do as you please, it gives you freedom from all the chaos of the situation. It allows you time to really process everything and really focus on yourself and not the sitch. It has really helped me make leaps and bounds when it comes to letting go and detachment. I'm just speculating but I think it benefits the WAS as well. It allows them some time to get a taste of what life without you is actually like, it likely also gives them some time to grasp the reality of what they are doing, just guesses though.
Catching up on your sitch I really think that her moving out would probably be the best thing for you. I know it's tough to see it but for your sanity and mental well being I really believe it would be a better option at this point.
