It occurred to me. I read that book by the writer from Sex in the City. He says, and men seem to concur, that a man who is in love with a woman will move Heaven and Earth to be with her.

Maybe you could make it harder for him to see you. Men often lose interest when the conquest is made. It's easy to say, harder to do, but protect yourself. You said the relationship is grinding you down. Maybe you need a break.

I know it's hard. You have my best wishes.
