We do travel together.

Business travel makes him feel important and relevant. Are there other ways to get that feeling? Absolutely, but he's like a petulant child (nods to barbie, I see what I did there) who sets his sights on the one and only way and digs in.

Horse with blinders.

Uncreative.

Writer, I think you are highly discounting the fact that I told him before we got married that I could never be with a traveling man. He never traveled before we got married, and the job he had did not require it. So add up: 1)I was open and honest about this need 2)It was not an issue when we married, and 3) he is now forcing the decision on me to D or put up with it.

I am not at fault here.

Marriage is the triumph of imagination over intelligence. Second marriage is the triumph of hope over experience.
