It occurs to me, Cali, that she is "trying" in her way. I doubt she'd have made that much effort to be "helpful" if not. She clearly didn't want to take your son to the party but offered anyway. That's a large departure from the past, no?
It sounds like it feels like she is not all in. I believe that. But she's not ready to walk away either. From a momentum viewpoint, that's a pretty big step for somebody in her position. And it's not unnatural that you don't yet fully trust things. I doubt she does either.
Patience. It's how you'll see how things turn out But wanted to call that out because it seems an important reminder while you're on this journey.
Feel better! AJ
