I feel your pain. Mine just picked up S for the day. I was trying to talk to him about some logistics stuff and once again he wouldn't look at me. At one point I stopped and said are we doing the not looking people in the eye thing again. I was trying to schedule an activity for him and S (that we had previously discussed) since we are leaving soon and I could see him thinking about how it would fit into his plans with OW2 as he was answering, since he was off work that week. I felt the rage boiling in me. After they left I texted him the day and time info and as usual, he has to let me know how insignificant I am by not opening it. I keep telling myself 3 weeks and I'm out of this part of the world (will have to come back on weekends and hopefully arrange movers). I told myself that's the last time I do him a favor. I'll just take S myself next time.
The new place will be nicer because he won't be there and his drama won't be there. You can't imagine how much more peaceful it will be not to have to deal with his nonsense. It will hurt at first, but it will quickly be preferable to be in his absence and then you will be complaining about the times you have to see him (like me).
