SE...I know you're heated. Just take some rest, but tomorrow, know that I'll be on your back again to get to the bottom of this.
You know you have it in you to really answer the questions and that there is a cause/effect cycle going on. It sucks to be on the receiving end of his behavior...my H hated it too and I was pretty infantile as well. Which triggered his comment "thanks for being calm and supportive" while it felt like a HUGE compliment, it was also a JAB...meaning "in the past you were a nag, unsupportibe and a total lunatic when I was going through hard times."
Remember, I was your H once, in many ways (not all). So, let's work through this together.
He's being an ass for a reason. We'll get to the bottom of it. Don't give up.
