Most divorce agreements have times in them to avoid this sort of conflict, especially in high conflict divorces. My ex and I have it but at this point it's there but we are flexible with each other because well, through the 8 years we managed to work together on this.
Your W was right. You really do make decisions really quickly. I believe you do that because you are trying to get out of pain. Each rash decision you make is because you think it's going to give you some relief. yoi quickly stitch up wounds hoping they will close and heal. But they reopen because it's not done timely with precision and thought. ( yes, I suk at metaphors).
I agree you keep calling her some entitled princess but you keep enabling her. But with the loose boundaries, not thoroughly thought through agreements which are done on the emotion at the time and change 5 min after they are made, everything is loosely interpreted and then she goes through the loopholes. Or maybe she really doesn't understand what the deal is right now. I'm a little confused because it changes daily.
Slow down. think. Because I know you are in pain but these rash decisions may ease it or give you comfort for the moment, but they just keep reopening again.
