I’m not sure what to do

What do I do in this situation?

‘27M’ I need to know what’s going on. Ive been seeing this girl for months and at first it was mutually just a situationship. Non-serious. Then she wanted it to be more serious. I’ve been single for years because I want my next girlfriend to be the last one. She got mad when I didn’t agree and we stopped talking for two weeks. She started seeing and talking to other guys and then reached out to me again. We started talking and then agreed not to talk to others anymore. It became more serious. But I was still on the fence about asking her to be my girlfriend. She’s 6 years older than me and I prefer it that way. Recently a situation happened where she’s convinced I was going through her phone and making another profile to test her and see if she was being honest with me about who was reaching out and tryna get with her. I always felt like she was honest with me so I never felt the need to try and go through her phone. But this situation came about and then she told me we need to take space and re-evaluate. So we did. It’s almost been two weeks and it seems more than ever now that she hates me. And she says I’m psycho and need help. I’m not perfect but I’m not psychologically unwell. I’m very kind and I have lots of people who can attest to this. The thing is, I’m not over her and I miss her. But I know she’s talking to others and recently she sent me a message about her being on a date, not one that she set up and that it went horribly and she wasn’t attracted. Then she added she’s sad that I’m a liar. And this was 4 days ago. I haven’t heard from her since. I doubt she’ll reach out again. If she has moved on and she wants nothing to do with me why hasn’t she unfriended me from any social media? I just want to know what to do and if I potentially have a chance at all to get her back?
