That would be all well and good, if it weren't for the reality that you previously withheld the phone from your D for no other reason than she forgot it in your car, and basically made her beg you for it.

NLW, it is OK to go through the different types of scenarios on what your H could have been thinking during the "Shopping Incident". The harsh truth is, his behaviours, even prior to that, were off the chart.

You are trying to rationalize and even justify his behaviour.

If I were in a store and met up with my W and the kids, and approached them and one of the kids told me to f off... I would have backed off, maybe felt a little sorry for myself and a little angry... and I would not have made a scene. Followed them around trying to get them to respond to me, humiliating not just them, but myself as well, in a public arena.

You H needs to figure out how he is going to a part of your kids lives and potentially, appropriately co-parent the kids with you. There's nothing you can do.
