He's pursuing you. I do hope you enjoyed the dinner and thanked him.
It's okay to appear interested in his conversations and you "might" try a few gentle touches to the shoulder, arm or hand and see how he responds. There is no set rule that say what is right or wrong when dealing w/someone in crisis. Each person will need to figure out what works in their own situations. If something doesn't work, stop doing it and try something different.
Follow his lead and see where it goes. When in doubt, do nothing.
Right now, he's trying on different masks to see which one will make him happy...but he'll discover along the way that until he faces his demons and looks within, he will not find that "permanent" happiness that he's looking for.
Keep the focus on you and your children as much as possible and allow your h to figure himself out.
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.
