(((G))) You guys have a tough situation re: comms. I can't remember, do you actually see each other for drop off/pickup? If not, unless it's about the boys, I'm of the opinion that contact could be scaled way back.
I'm glad you got to say and figure a few things out- for you, not for her- b/c you're right, she's probably not listening. You guys have one of the best chances I've seen around here for a great co-parenting (and possible friendship) relationship. But it feels like you need some period of detachment before moving into that- a little space. Because you guys kind of easily slid into this murky, not sure what the relationship is, kind of place without a specific break (IMO). It's kind of confusing and ambiguous when there's no end/new beginning, I think.
