T, ok, major props to you for rubbing his butt! LOL!
And I know how hurtful it is to know that he is going away with her and I am sorry.
I also know how tiring this can be. I used to look at him going away as a reprieve from having him and his nonsense in my face.
I know you can see that he is not happy. Between his physical health and his state of confusion, I think he has no idea what he needs to do to be happy. And so, he is continuing in this vein because I honestly dont think he is up to doing anything different right now.
