My ex-boyfriend always pays attention to my circle of friends. For example, if I send a story that doesn't make me happy, he asks me what's wrong.

Personally, I think that since such a thing has become an ex-boyfriend, maybe you have a new boyfriend now. In that case, I suggest you block it! Or the recent resistance to black! Reduce unnecessary connections and admit that there is still hope between the two. It may be good for everyone to have a purer love stand in two new relationships. This is not selfless, otherwise it is not selfish, just for everyone's consideration. When you destroy everyone's hope so decisively, maybe everyone can find better love in the future. Isn't life like this?
