Need advice on interacting with WAH

[AntoniaB]

My old threads keep disappearing so I have to assume those who've talked with me know who I am. But anyway, I'm a bit stuck on interacting with my WAH.

We are only in contact over legal stuff now. He filed last week; I have to be served in the courthouse this week (my choice) and I'm filing the petition to answer then with the SA. My H and I have been cordial for the most part when we interact. But the contact is down to a minimum.

I'm doing the whole GAL thing very well and today I had to see him for about an hour as he had to come take this aquarium apart that I was making him take with him. I could have been gone for him showing up, but ever since I made him return his keys, I have not liked the idea that he'd be here when I wasn't. I am calm enough now that I can interact with him and have it NOT go bad at least on my end. I approached today as the type of day where he sees that I'm happy, I'm centered, and I'm ok without him. We chatted pleasantly while he was here, and for a lot of moments, I think both of us almost felt like things were the way they "used" to be.

That is, until he did one thing to anger me.
