I'm glad you offered a place to stay, but wasn't surprised he said no. By offering a place, it let him know that you were listening and had some empathy for him. Now, it's in his court and he very well may continue to stay w/his parents when he comes to town.

As for him not sleeping well last night...it could be that he tossed and turned thinking about his situation and what he's going to do. He could very well have taken some OTC meds and have made him sleepy as well...but time will tell.

Continue as you have been. Yes, he's waking up just a wee bit, but he still has a ways to go. Keep up the good work.

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.
