Why would my ex do this?…?

[Anonymous]

Ok so I dated a girl from my workplace for around 6 months, things were good but eventually I just couldn’t communicate with her over text after I left the job and she took everything the wrong way which led to her upset. She blocked and unblocked me multiple times until she blocked me for a month, I think she went back to her toxic ex for that time, when she unblocked me but she didn’t reach out and neither did I but she created a new Instagram account and sent the girl I’m just getting involved with personal / slightly private stuff she found online of stuff I posted many years ago e. g forums including a pic of an operation that I had a while back, bare in mind that was one of my biggest insecurities that she knew about. Like I say she never reached out, I’ve blocked her now, I confronted her over message but she denied everything playing the fool, I’m just trying to understand why she sent her that as when we were dating I never saw her as the crazy ex type. The current girl had to delete her Instagram.

She felt deserted once you quit. You were just using her out of convenience. She trusted you but should not have. I knew I should have not gotten involved with someone at work.
