There is no way of telling when or if your H will wake up. Even if he does I wouldn't expect an explanation for "all of this", he might not have one that he can articulate. I would be willing to guess even if he did it would simply be MLC and he might not even realize that is what is happening.
As for not noticing you, he did. I have read all over that even though it seems they don't pay any attention to you they are actually watching you very closely.
I bet his mom was acting so happy because she was very uncomfortable with the situation and didn't know what else to do. She is trying the best she can. This usually is not easy on the extended family either. They might be just as dumbfounded as the rest of us and this is her son that is making a mess of your lives. She probably just wanted to enjoy a day with him and the girls. Sorry I don't know her stance on your sitch but this might be the case.
I hope you had a nice day today and enjoy your evening out with friends.
