Girl (26F) I (28M) was seeing said she really likes me, but she's not ready for a relationship

We met on Hinge and for two months we talked every day or so, but we only met up 3 times because I was traveling and one of us kept getting sick. I wasn't sure about her, we had some differences but I was still willing to keep seeing her. On the third date, we had a breakthrough, slept together and had a wonderful time, and it actually made me more interested in continuing.

Soon after, I started feeling her pulling away, so I asked her what's going on, and she told me that she really likes me and that we were a good fit, but she didn't feel ready for a relationship due to personal issues (parental, depression, etc.), that she is scared to start something she can't give 100% to and scared to hurt me, and the only way she sees it could ever work out is that she messages me when she's ready. I told her that's how people let others down gently but she insisted it's the truth. I offered keeping in touch but she says that she can't be friends with someone she's romantically attracted to. I didn't push much further because I knew that there was no convincing her, so we left it at that.

Three days later, she messages me "why do I lowkey miss you", and started talking to me again about things that are going on with her life. I took a firm stance and told her that I don't want to be in a dynamic where she can dip her toes in without committing, and to message me when she has decided what she wants. She apologized and I found out later that she removed me on Instagram. That was a month ago.

The problem is, out of the 15-20 people I've slept with, I've never felt more physical chemistry than with her and I can't get over it. I thought I could get over her but I keep thinking of whether or not I should message her, and if she declines again, then at least I'll have tried all I can

What would you do in my situation? Move on or message her?
