Rocd and a ex partners reaction

Hey everyone , so about 2 months ago my partner and I had decided to mutually split up, on my end it was due to my inability to fully manage my relationship OCD symptoms due to circumstances and my tendency to believe that they were really my desires despite them causing me(and partner at the time) distress. Anyways after the breakup I found out that my ex partner held a lot of resentment towards me because of my actions during the relationship like my impulsivity and compulsive confessions which were hurtful and eroded trust over time. That I completely understand which that was a big reason why I decided to end the relationship as I didn't like how I was as a partner towards them and didn't want to further hurt them. However the way they went about their side of things really affected me. Not only did my ex partner become cagey with me but they also went behind my back and started to be very obvious with their involvement with a mutual friend of ours. I tried to respect their space as by this point in time we had already broken up but it had not even been a month since then, and they also knew I was able to see everything hinting at their new relationship on social media. When I called them out on this they proceeded to bring up everything wrong that I did during our relationship and they held on to stuff that I already felt immense guilt for and stuff that I had already acknowledged could only be worked on if I was not in the relationship. Moreover they brought up subjects that I had confessed during periods of OCD spirals and compulsive confessions, which they believed were true I guess. Saying that essentially "I hope you get to do those things". Furthermore they also said something along the lines of "I know you have OCD but OCD doesn't make someone say fucked up things to their partner over and over again". I thought I was on the right track by making it clear that I wanted to make things right by separating and dealing with my symptoms on my own time and not having someone I care about being involved, but them doing and saying all these things eventually did lead to me to acting out on my compulsions which involves sleeping with men even though I am a lesbian. In a way it was a form of revenge for them moving on so quickly but also a form of self punishment because of all the shame I carried after that relationship cut off. Does anyone else with ROCD carry this kind of guilt after a relationship ended, this truly sucks.
