Hey FG -
I agree with GG (And I usually do) - no contact is a way for you to pull yourself out of the panicy feeling, the negative downward spiral. Oh, he seems moody, oh, he just snapped at me, that reminds me of the time last month he was harsh with me, (worry worry), then I think I will snap back at him, etc etc.

Just do your thing and have fun doing it and recharge yourself. If he wants to reach out to you, he knows where to find you.

About the Holiday Party - I don't know enough about your husband and situation to offer an opinion on that. All I know is this week he is quieter than last week.

Maybe the right thing to do is make him aware of the party, but don't directly invite him. "The holiday part is the first week in December."

Keep in mind this is just a holiday party. It's not the end of the world if he decides not to go. It's not eternal bliss if he decides to go. It's just one party. You can hope he will want to go, but don't expect it, and be careful to not be too deflated if he doesn't want to. Just a party. You can have fun either way.

Take care FG!
