I(22M) need relationship advice as I'm clueless about what to do next....

So finally after 6 months of my breakup I (22M)came again into relationship with that girl(22F) (check my profile for context) but there was nothing like it used to be in the past. This time I was getting blamed for everything like it was my mistake I caught her, it was my mistake that I broke up, I'm the only one responsible for her mental breakdown etc. things went like this till June 2025 and after that I got so much frustrated that I ended the relationship again this time there was no resistance from the girl, as she did the last time and the shocking part is she got into a new relationship just after 2 days of our breakup. The guy was his ex (the person with whom she was in relationship before me). But after breaking up also she used to contact me on regular intervals and she still blames me for everything that had happened since we had a physical relationship as well so she says that I have used her for my lust and as I got bored I left her. Now she broke up with that guy as well and try to communicate with me every single day but I don't want to talk to her I have already blocked her at every socials so she showed up at my house one day and in that pressure I just talk to her once or twice a week. She asked me to be in touch so that she can share her things with me. So I just need help what should I do in this case I'm very helpless and clueless about what to do.

(I'm not saying that she is the only one wrong here maybe some of my actions can be wrong as well. And one more thing to add give a look to my last post before reading this)
