Look, this either is a real boundary with you, or it isn't. It seems to be more of a "geeIwishyouwouldn't," to me. Your words keep SAYING that this is a dealbreaker for you, but your actions are that you keep taking him back -- and allowing him to do this -- without any consequences.
What boundaries (if any) did you put in place back in July, when you last posted about this?
Of course he turns it around on you. They all do when they are cake-eating. Just tell him you wouldn't have to snoop (gather intel as Puppy would say) if he wasn't lying, so put blame where it belongs.
Puppy is right can't have boundries that you don't intend to enforce. I know it is a scary thought. I hve been down that road and Puppy said the same thing to me.
