If you read the situations that got to R--where the WAS ceased any affairs and got on-board trying to save the marriage--most neither turned on a dime weeks after joining nor took many years. The sweet seems to be 6 months (early) to 2 years (late). I'm impressed you're finding the strength to validate, not cave on moving out of the bedroom/home, and not act cold or mean. It's a marathon, keep at those GAL/180s! If you need to vent, find safe places like here or the gym.
