I'm around my H every day. When we are around other people, he definitely isn't himself. He's generally pretty nasty.
When we are alone, he is generally polite and nice. However, he is still not himself.
I can think of one evening in months and one morning that I can look back and say he was completely himself. Talking like himself, acting like himself.
There were other times that seemed pleasant enough but then when I reviewed them in my mind a few hours later I realized how truly strange and bizarre they were.
He may be here, but I feel like a widow because the man who is here is not the man I married and knew all these years.
