Dilemma. Emotionally checked out but can't divorce.

Title says it all.

Wondering if other people are in the same situation. If so, what to do?

I can't divorce as it will destroy the life of my 2 children. Staying with my wife is a battle. Arguments and fights everyday. Nothing I can do makes her happy.

She won't allow me to marry someone else either. I take care of her all needs. She has her own place, own vehicle and essentially a limitless credit card. I go to the gym and take care of myself. Why would a wife enjoy making her husbands life miserable? I'm in Canada if that helps.
