I am nc. Today I got a text I think about me, but not to me- like sent by mistake. (... .)
Hi atomic popsicles. Just adding a perspective. It didn't look like a mistake. Anyway, he looks like he's trying to pass judgment on you. These kinds of statements seem created to provoke a response whether a person knows it or not. If it's drawing you to respond to it, try to keep in mind the bigger picture.
I don't know how practical NC is, but blocking as an option helps. I didn't block my ex, but I prepared myself mentally for her to continue dysregulating at me by text. Another option for you is simply not to read the message. Most phones give notifications. You don't even have to read those. Just swipe it when you see the name. You can even turn it off it you don't need the app for work.
This only came up for me once as she kept up her end of the NC, but the important thing is to have a view of what you're going to do. Hope you get some rest.
