I have been following your posts, you are getting some good advice here. You are in a tough place right now, I know it's hard to know what to do. I can understand why you are nervous about him coming home.
I think Job says it well, to just be yourself (I found that hard in the beginning because I didn't know who I was anymore!) Just keep busy and do what feels right as each moment passes. Be friendly but indifferent. Hawho is a great example of how to be with the MLCer in the house.
I have no advice about the A, other than to stay true to yourself. Focus on you and be kind to yourself. Good luck today, keep us posted.
Oh, and my H changed his underwear style too. But I noticed on our last vacation they were back to his normal style. Lol.
