Going Anon - Vent about Ex bf

I need to get this of my chest. Long story short:


Couple years ago I left my family, friends, and work, to be with my LDR bf in PA. Everything seems great for almost a year. We went to school together, so knew a bit of him and his family. I literally gave up my stable life in LA. Only a couple weeks later a friend to me and alarmed me he was trying to flirt with her. When he came from work I confronted, and he admitted his act. I packed my bags and flew back to my hometown the next day while he was at work. He had history of cheating, and that was a slap on my face. I was blinded by love, so badly I ignored all the red flags.
Fast forward, I got into a new relationship over a year after the terrible break up. I admit, I love my fiancé but I am still haven’t move on 100% from the pain. I often remember about the past. Sometimes I feel lucky I got out, sometimes I feel like crying because of the pain the betrayal caused me. I did went to therapy. It helped but not 100%.
I recently got engaged and maybe ex heard it from friends. He called me a few times using no caller id, asking for forgiveness and asking me back. FYI: He had a few short relationships after me. He just has so many flaws, it’s going to be tough to find someone who loves him unconditionally. I hope he quit contacting me and my bestie to tell me he wants me back. My fiancé didn’t know he is trying to reach me. I am just afraid ex is going to stress me out with this constant calling. I changed my number today.
Vent over.
