I am sorry your H is acting so selfishly. I am going thru some custody drama as well and it's no fun.
The one thing that works in your advantage is time... Your H might be wanting this now, but as we know WAS change their minds on a daily basis. And a year from now, who knows where we will all be...
So try not to give too much weight into it now. Besides, there is nothing you can do about it (or him) right now. I know it sounds simplistic and I think the jist of this sitch is just how hurt you are feeling about your H's selfishness. Just when you think a WAS cannot do or say anything more hurtful than what they have so far, another thing comes out of their mouths. At least that is how I feel many times.
So hang in there and focus on what you can control now. Heck, isn't our daily life challenging enough already to be worrying about what happens a year from now? (If you don't believe this, just think about where your life was a year ago.)
((((hugs))))
