some people just are not into blocking.
blocking may be one tactic when you need to build high walls to in order to detach or avoid someone.
if you want to detach, it will not come through blocking her, or her blocking you. it will come through letting go and being emotionally done.
Fair enough, but it seems OP is indeed one of those other people. If her social media interactions with him are making him ill, that's a clear sign that staying in touch
and detaching might not be a realistic prospect.
Maybe I'm extreme, because I never understood people who stay in touch with exes, especially immediately after the break. People need distance to clear their heads and see a relationship for what it is, without getting sucked back in by oxytocin and dopamin clouding their judgement.
It may be different if you meet up with an ex-lover a year or two after the last contact, but leopards generally don't change their spots, and also you never completely fall out of love. More often than not, remaining in touch just leads to re-cycling.
It sounds as if Anonymous is done with that.
