I went no contact on my FP around last spring and kept my resolve to go and stay cold turkey.

...Except she keeps popping up. Never directly, but around. I never react to those, not wanting to fuel the fire and get sucked back in. It's like a drug. One hit and there I go again.

A friend of hers who I never talk to, contacted me. There was no talk of the FP though. I didn't think much of it, but there was a little itch in the back of my mind. 
She made posts about me on social medias, no names named but obvious enough
Tags me so I get notified indirectly
She follows my social media with indirect account.
She sent a letter to my parents.
Stuff like that. Around me but never direct. Keeps herself far enough but still around.

I am confused and frankly a little scared. What's going on?
