I suspect she had some idea of where his glassbowlness was coming from; often others can see the ways someone is acting out of trauma better than the person involved can see it (particularly if this is the stage before the person involved realizes they even *have* trauma and the way that they were raised was abusive). “I’ll reconsider the divorce if you go to therapy” sounds a lot to me like someone who recognizes that the bad behavior comes from something that therapy can rectify.

I’m not saying trauma is an excuse for bad behavior, just that a lot of us are inclined to be kinder on people when we understand they’re being jerkbags because of pain rather than malice. And then the jerkbag needs to start working on healing in order for that kindness and compassion to continue.
