SP had a glimpse of hope and I need help

To set the scene, I ended things with a guy because after a streak of flakiness, no communication, and the straw that broke the camels back, which was him confiding in me about being down bad over another girl. We had grown close and had three great back-to-back dates which always preceded both of us texting about how we were excited to keep doing things together. We started talking with both os us being admittedly avoidant and coming out of abusive situations. The way he made me feel in person tied to our conversations over text and his reassurance despite his actions made me get deeper feelings than intended.

After I ended things, I got super into working on my self concept. I let how he made me feel reflect the way I felt about myself. I used mirror work, repetition, and subliminals. I noticed a change in my confidence, how I interact with people, and made steps to become who I am meant to be. From there, I began visualizing him and us. It was surprisingly easy for me to detach after visualizing moments of him confessing his feelings and our future. As I began having more confidence in myself, I stopped doing this because I realized my worth.

He randomly reached out to me recently, and I tried keeping it nonchalant, but he truly said everything I had wanted to hear before. He was sorry, he wanted to see me to talk things out, he wanted things to go back to the way we were. I folded. Since that conversation, he has gone back to the ghosting and apologizing cycle. I also went back to letting my emotions get the best of me and went off on him over text.

He has not responded, but I am struggling with feeling like I tore down my new identity for him. I am back working OT on my self concept, but that glimmer of hope he gave me isn’t going away. Does anyone have tips on what I can do?

TLDR: Need help with man coming back the way I intended, but he went back to old ways the next day.
