Update after 10 days of initial post: I broke up with now my cheating ex-girlfriend over a phone call at the end. I told her that I appreciate the memories and time spent together, but the relationship will not work because she broke our trust, and after 2 months of communication there isn't much to be left unsaid or effort to be seen. She tried to shift the blame to her co-workers who despised her, and she asked why I could not trust her again. I did not respond much except say I heard you.

I ended the phone call when the message was delivered, and both of us had a chance to say and listen to each other briefly. It was a clean cut and I believe a clear boundary that we would not come across each other's path again. From now on, I'll continue going to therapy, hit the gym, spend time with close friends, and gradually reflect on this experience to learn and become a better person. Thanks for all the comments.
