Jon may have made some mistakes in this situation, but to me the W sounds a bit crazy and immature to lash out like that, make a comment about the daughter, and then just walk out, and sit in the car crying/pouting. This does not sound like the maturity of a 32 year old woman.
I'm trying to take a step back and put this in perspective of their entire history. I'm starting to sense she's very insecure and immature. She had a PA because she needed attention, spent Jon and herself into oblivion and then got upset that he wouldn't get her out of a monetary jam a couple of months ago, and now exploded when this came up. Jon was just trying to be a good father.
There does seem to be a communication problem, but it may not entirely be Jon's fault. I have been hard on Jon in the past, but I am starting to get the feeling no matter how well he DBs her, it's not going to help her at all.
