Hoping you are doing OK and want to just say that I (and many others) are here for you. I am going to read through your whole thread-- I don't think I started at the beginning. I think our Hs are very similar in a lot of ways, and if mine does decide to go he will be very much like yours, unwilling to admit, ever, that (if) he made a mistake.
Can you talk more about the anger? Are you not OK with him having the kids more? (No judgment, I wouldn't be either... I am actually haunted right now by the idea that if I just say please go I'll get a better deal on the back end in terms of the house and the kids when he's still feeling guilty). Or is it more generally to be in this situation and his unwillingness/inability to really examine what has happened and if this is the best path for all of you-- including the children-- going forward?
Any positives about the house sale? Any ideas about where you want to live next?
