Glam,
He's still in the last stage of his crisis and he's still trying to convince himself that the two of you have differences. Pay his comments no mind. He's testing you to see how you will respond. They tend to do that more frequently towards the end.

Also, do not ask him about his meds. You are putting yourself in the mother mode to his child mode. He's an adult and should know that taking them keeps him on a smoother path. He'll figure this out on his own.

His comment about you enjoying your time when he's not around...again another test to see how you feel about him being around and on a permanent basis.

Glam, he's right where he should be. He's doing all of the things that I would expect for someone in the final stage. YR's, BND's and DebM's hs did the same thing. They want to make sure that the changes you've made are permanent and that home is really a safe place to return.

Please do not lose your patience now. It's very important to dig deeper for more patience. It's going to be worth it once he's home and then the real work will begin for sure.
