Ex called me crazy and manipulative after telling her I was SA’d

This is the first time i’ve spoke about this since it happened but like the title suggests about a month ago i was SA (not by my ex wBPD). A couple days after the discard. I was already not okay and being reckless and making bad decisions and unfortunately I was SA’d.

Over the holiday period none of my immediate friends were in the country, I had no one to turn to. I frantically reached out go my ex wBPD since I trusted her and I just needed to talk to someone. I was at such a low point already and it was like the cherry on top.

How did my ex respond? She called me crazy and said I was trying to manipulate her. Along with a barrage of so many other things. Reading those messages was my tipping point. I went into such a dark place thinking I deserved what happened to me for how things ended with the ex.

Only now, almost 1 month later am i realising how fucked it was. For context we’re both F and so to hear this come from another woman’s mouth (who mind you has had similar experiences in the past) was disgusting. I only just mentioned this to my bestfriend yesterday and her reaction made me realise how immensely fucked it was. Romantic feelings aside, I think most people stranger or not would show a SLIVER of empathy and compassion but not these guys.

The level of betrayal is just incomprehensible. Thoughts? Am I valid in feeling angry about her reaction to it? How can someone be so cold?
