Just an update. H has spending a lot of time with me. Talking a lot. Definitely OW withdrawal & depression. We have been talking about him moving home, but he is afraid I will find him boring and I will leave him & he will end up alone. Doesn't even make since. He has "closed the door" on OW and "can't open it again". He is living alone at a buddies house(buddy moved away and can't sell home), but if he moves home he might end up alone because I will leave him. Sounds like depression talk about being worthless and me not accepting him now.
I guess I just need to wait out this phase and not pressure.
