Lou, I am in total agreement w/Sotto. Your h is still in crisis and as Sotto pointed, out, they can only focus on one thing at a time, especially when it comes to dealing with people. It's not that he's forgotten you, but he's still compartmentalizing things and until he can get himself sorted out, that's most likely the way he'll continue to operate.
I wouldn't be in too big of a hurry to post to him when he posts, i.e., take your time about it. I would post to him once in a while, especially if it's about something you know that will interest him, but keep the posts short and light. Too much posting may send him back down into the rabbit hole. Allow him to come to you. I think the holiday may have set you up for a little bit of "expectation" and when it didn't happen you were just a wee bit disappointed. Lou, his brain is still scrambled and he could only handle one thing at a time and it's not about him forgetting you...he didn't.
Try to keep the focus on you and yes, dig deeper for patience. His reconnection is going to take a lot of time and he's still not ready to come out of the oven on a permanent basis.
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.
