Trying to recover from a situationship that ended horribly lol. Need thoughts and opinions

I’m 21M and got involved with a 21F who initially cheated on her boyfriend of 3 years with me. She broke up with him right after, but yeah—huge red flag I ignored. We ended up getting really close over a couple months (trips, constant talking, met each other’s parents). She wanted something serious, but I had trust issues because of how it started. We agreed not to pursue it, but kept seeing each other anyway.

We had been seeing each other for a couple months after she broke up with her boyfriend, and toward the end we were both talking about how we needed to stop. Problem was, we were terrible at actually doing that—anytime we talked or saw each other, we fell right back into it.

Then one day she’s telling me she loves me and wants reassurance I’m not seeing anyone else. A few days later, after acting cold, I catch her at another guy’s place (a guy who had recently hit her up). She lies about it until I show proof, then says she was just “getting to know him” and claims nothing happened. I didn’t believe her—she has a past that already made me uneasy, and she was there for hours late at night. This was the first time I felt cheated on. I reacted emotionally, said some mean things, and ended it, then blocked her.

Two months later, I apologized for how I handled the ending. Regardless of what happened, I wasn’t proud of my reaction and it didn’t feel right to leave it off like that. She responded a few days later saying she doesn’t accept it and that it “changes nothing.” I suggested we talk it out so we could both understand each other’s perspective, but she said she didn’t want to revisit it and asked me to respect her boundaries. I did exactly that—just replied “okay” and left it there.

After that, a couple weeks later (while I was on vacation, which she knew about) she randomly blocked me on Instagram and Snapchat (even though I had already removed her) but left my number unblocked, then two months after that (present day) blocked me on TikTok—even though we weren’t connected there.

What confuses me is the repeated blocking over time. I haven’t reached out or bothered her at all. It feels weird to keep blocking someone you supposedly don’t care/think about, especially months later. I always felt like she wasn’t thinking about me like that anymore, that she had replaced me and moved on. Same way she did her ex. But that doesn’t add up. She didn’t even block her ex lol, I am pretty sure out of all of her past “flings” I’m the only one that got blocked like this lmao.

We’re in the same work field and I hate how things ended. I am going to see her around at one point, and tbh she is still someone I care about and I enjoyed being around her.

At this point I’m not looking to restart anything. I’m just curious on what you guys think. Why is she doing all of this? She told me she was an avoidant, which is adding up here given how she wants to avoid what she did and paint herself as the victim. But like what could she possibly want from me. Given what I know about her I’m assuming she wanted me to chase her, but instead I had given her the “okay” and ig she didn’t like that. I don’t mind texting her again, I can engage in a fun toxic kinda hot chase but there’s fine line between chasing and whatever the fuck I’m expected to do here. Does she just hate me THAT much? Or does she think about me that often and is starting to feel bad for what she did? Thoughts?
