Don't drink the kool aid! Your h is having a temper tantrum and this is exactly what the mlcer does when having one. He's punishing you for not allowing him to have Tuesdays and he wants you to feel the pain and hurt.
As for FB and the ow, they most likely were still an item and he just didn't have her "added" in Facebook for a while. Your going dim had nothing to do w/his recent FB antics. Stop blaming yourself for the way he behaves. You have no control over what he does or says.
Mlcers are very selfish, self-absorbed individuals and have a way of "punishing" us when they don't get what they want. You can't waiver from your boundaries when they do these things. If you do, he will know you don't mean to stick to the boundaries at all and he will see them as idle threats.
Pick yourself up, dust yourself off and continue moving forward.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
