Hi, (m) 23 I have a ex (f) 23 who went cold turkey on me after I wasn’t ready to talk yet after a fight from my collapsing at work. We were together about 10-11 months. She has been the sweetest girl and dropped everything to move an hour and a half with me after my parents kicked me out and abandoned me so at the very least I’d have a bed. She has started “talking” with my boss/friend the day of the break up and it’s clear to us and all of our friends she’s using him as a crutch for me. Now for context she broke up with me once before about 8 months before this relationship because I told her I loved her and she said it got too serious for her. I am her first bf, but since this break up she’s been textbook DA and FA. My other issue is I called her during the NC because my boss was telling me at my house how he was gonna fuck her and use her. When I told her about this she ignored and wanted to literally nitpick stuff in our relationship we had already worked and healed from basically “well you did this to me” and when I said we worked and healed from it she moved on to something else almost as if she was agreeing. My issue is that she’s a super headstrong woman who will not back down if it’s something she truly believes in. If it’s something she’s not she’s usually only using it as a cover and has come back and admitted to doing so several times in the past. She only actually responded to me when I told her I don’t hate her I love her and I want to work with her. And that ended up in her sobbing saying she can’t have the conversation anymore. The next day we fought on text and she was textbook DA writing everything as an attack and even going as far to literally avoid my questions like the plague only to say I’m not giving her her space. She said she was gonna block me 3 days ago but hasn’t. She’s been logging in on my accounts multiple times over the past few days while changing all her accounts like a one way street. I want to reach out to her and set the boundary of “I don’t feel it’s healthy to have access if truly moving on I still care and im here and something we’re to change and want to talk further im here and if not I wish u the best” she’s started posting on social media about what’s she’s doing as well but only on Snapchat which I’m sure is purely for seeing if I’m watching. In the last fight I said I hated her for the first time ever and her reactions changed to still being upset but now she was acknowledging what I was saying, but we were both so heated it didn’t go anywhere. She said she was gonna block me and usually has no problem doing so with other people but never actually did it to me. It’s been 2 days since true NC (first time for even 24 hours of no contact since we began talking in the beginning of the relationship) and I want to break it to set this boundary while also trying to show that I still care and don’t truly hate her. She has never done anything but to love and support me and Ik she self sabotages a lot and will still pick the hole at times because she’s scared of the judgement from backing out of the hole. Which is why I’m willing to forgive her on top of that we did have an open relationship prior and even when she had a side relationship it only fizzled out due to her attention and time still only being focused on me. During the open relationship we never really fought and didn’t have any issues with it. So her having sex with people doesn’t bother me only the emotional attachment. What do I do

Tldr: ex wanted to go NC continues to msg only to fight but relents when I say I still love her and is going after my boss as an emotional crutch while still trying to monitor and see if I’m watching
