I would stay the course. When you do have contact w/him, listen and validate. If he talks about his new place, you could ask him some very general questions and if he asks for your opinion, then give it to him. I wouldn't increase the amount of contact just yet. Notice how it's still all about him? That tells me that he's not ready to have a grown up relationship yet. I think he wants a friendship (one sided) at this time.

He's still very much in replay and he's telling mom (you) all about what he's doing. Don't get discouraged. Your man/child still has a ways to go.

Stay the course.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
