I agree with Chris that moving out of the bedroom is a bad idea. My best suggestion is for you to do what worked for me. Tell your H your honest opinion about the future of your relationship if things don't change. I told my H that I couldn't imagine the two of us continuing on alone together once the children were gone if things didn't improve. Theoretically, this gave him 5 years in which to drag his feet, but realistically he knew he had to face up to the situation immediately.
