I think I understand what you’re saying but you need to stop using NGS as an excuse.
You don’t ever have to state your boundary. I didn’t make a grand statement to my exw because of what she did I wasn’t going to do X. I just did it. If I got a text about the kids I would respond when I felt like it. If I get one about password for such and such I ignore. It took a really long time and lots of rejections for her to get it. If she’s that stupid and can’t figure out why she is completely out of my life other then the kids that is on her.
