There's nothing lonelier than being trapped in an unhappy marriage. You have a couple of choices. Talk to him and see how he feels, consider going for marriage counselling. Even if he doesn't want to go, you could go for counselling for yourself - might help you decide if you want to stay or go. Or you could just say "I'm done" and walk away. Life's too short to be miserable. If you don't choose one of the options I've listed, you'll just waste your time until he leaves or one of you dies. A terribly unhappy prospect! Thanks for sharing - I hope things improve!
