How do you deal with broken agreements? Like, we had an agreement, verbal, and I confirmed the agreement in writing, and he stated in writing that he agreed with all this.

Then he goes completely crazy, tells me that he never agreed to it and after a big fight over the text, he emails and says that he never agreed to it and that we no longer have an agreement (on which I laughed - how can we both not have an agreement and no longer have an agreement).

There is no way to enforce it. I think that's one of the reasons I divorced him https://onlinedivorcewa.com/washington-state-divorce-laws/. And he's not going to change. So I guess I should just look forward to it. But I was expecting this, so I sent an email. I think it doesn't matter.
