Is it possible for me [27F] to repair my relationship with him [27M]?

Three weeks ago, I started talking to someone, and we quickly hit it off. We spent hours texting each other every day and enjoyed a great connection. We met in person for the first time a week after we began chatting, and I felt it went really well—he even texted me afterward to say how amazing it was to meet. Just two days into our conversations, he mentioned that he had deleted all his dating apps and wanted to be exclusive because he felt positive about us. However, during our first in-person meeting, the topic of past dating came up, and I honestly shared that I had slept with eight people over a five-month period. He seemed to handle it well at the time, but a couple of days later, I noticed he was becoming distant. His texts became less frequent, and whenever we tried to make plans, he would cancel, citing “family emergencies.” He insisted that he still liked me and wanted to pursue a relationship when things settled down at work, but I couldn't shake the worry that it might mean he was losing interest. Despite this, he continued to text over the following weeks, albeit not as frequently as before. He reassured me that he really liked me and wanted to be with me, which gave me hope. Recently, he opened up about why he’d been acting distant. He admitted that he was judging me for the number of people I had slept with in such a short time and was concerned that I’d just be another casual encounter for him. I did my best to reassure him that I was serious about wanting a relationship. Tonight, the topic came up again. He said I came across as intense, considering we had only met once, and my constant worrying was making him put his guard up. He assured me that when he said he wanted things to work between us, he meant it. Still, I'm afraid he might be ready to walk away because he can't seem to let go of my past. He mentioned he needed to sleep and that we’d talk in the morning, but I'm anxious I'll wake up to a message saying he’s lost interest, especially since he deleted all of our saved conversation messages. How can I address this and prevent him from completely walking away?
