Heather, I sense from your posting that your are frustrated and disappointed.

nothing has changed Your monitoring the sitch. Good.

For the most part, he hasn't been getting to me. . .all I said was "This is getting old" You were in control of your reaction to H's actions. Good.

Our first MC session is scheduled for the 13th. I would be pretty surprised if he still comes. Even though there is a history, to support your prediction, you don't know what's going to happen on Monday, so don't waste energy stewing about it today.

Right now, I'm trying to stay calm, not to let him get to me. It sounds like you're doing a good job of this.

I think it might actually be rude to do this in front of him and I hadn't really considered that before. It's good to try to see our actions from our S's point of view. It keeps us honest and thinking outside our box.

I am wearing my rings. . . Giving him as much space as I can. Doing your thing, not playing the game and not taking the bait. Good for you.

Heather, you are one tough cookie. There were some better times just recently, take some energy from them. I hope that H does go to the counseling. Don't let him drag you down. Passively drag him up to you.
