This is all a bit of a tawdry tale but...
Earlier this year my partner started seeing another woman (N) behind my back. It was in essence an affair although he says (and she admits) that he told her it was only ever about casual sex. They met on a casual sex type hook up site.
Anyway, it all came out because N got hold of my social media details, and messaged me, then spent hours giving me a highly embellished version of the truth.
Partner and I split up. Her hope, as I understand it, was they would get together as a proper couple, start going on actual dates rather than just meeting for sex. That didn't happen and as I understand it they saw each other no more frequently than when he and I were together.
A few months ago he contacted me, and we started talking, just as friends. This kicked her off and she messaged me again with a load of vitriol. From that point contact between them reduced further.
More recently, after a lot of talking, I felt maybe we could try again, very slowly, just dating, no sex etc. But I said that he would have to cut N off completely (by this point he was only seeing her intermittently, purely for sex. She was also shagging a number of other men and had been throughout. She told me she hoped it would make him jealous and he would ask her to stop. He didn't).
Anyway, him telling her that he wouldn't speak to her again has set her off like a rocket. She sent me 4 messages yesterday on SM (before I blocked her). Before blocking I did message her back and clearly tell her not to contact me again.
Today she has sent 2 more messages from accounts she has created purely to message me, content is her generally being spiteful and vindictive. I will block her again but am I within my rights to report her for harassment if (as seems inevitable) she contacts me again from a new account tomorrow?
