I didn't ask any questions or really reply, I just listened. I want him to process it in his own time & sure he'll talk if he wants to.
Thats the key, you are doing great, step back and watch from a confi place, this is his road and its extremely important he walks this road himself.
You have been doing great, and it seems that its working, keep doing what it works.
Remember he has to figure it this out by himself and deal with fears that he has inside himself, he wants to go away with you? I think you need to be patient and don't be involved in going away with him, not yet.
He is probably going thrue a lot of emotions, some of those make him feel high so thats why he wants to go away with you, in my opinion he is not ready to have a chat about life with you yet....it requires more time, as an addicted he might be going thrue a emotional withdrawal from you so thats why his ups and downs, let him get a balance first, you will be able to see once he is more balanced
