What should I do?

Last October, a girl from church whom I had a slight crush on asked my sister for my number. She expressed that she wanted to get to know me better and was interested in me. Initially, everything seemed to go smoothly as we chatted and connected over text. A week later, I suggested going on a date, which she agreed to. However, when I checked in about her availability for that Sunday—since she was busy with the worship team—she said she couldn't make it, so we rescheduled for the following week. But when I reached out that Friday to confirm if she'd be free, she started coming up with excuses, mentioning concerns about being seen together by others from church. This shift confused me since she had seemed enthusiastic before, so I decided to cancel to avoid complicating things. Fast forward two weeks, and we hadn't communicated much. I asked her out for coffee before a youth event, but she replied that she felt something was off and didn’t want to meet up. In January, after she finished her finals, I reached out to see how she was doing, letting her know I was there to listen. She responded with, "Hi, thank you for your concern. As I mentioned before, I’m not looking for a relationship right now and I'm not ready for one. I’ve realized I don’t have feelings for you; what I felt was just admiration. I really appreciate your kindness, but it’s making me uncomfortable. It’s probably best if you don’t wait for me because I don’t want to hurt your feelings. There are many other girls who would be a better match for you." I can't shake the feeling that I rushed things and crossed her boundaries, and now I feel terrible about it. She's the only person I genuinely like, and I had said I was willing to wait for her. What should I do now? Can I do anything to help the situation, or should I simply wait for the right moment to apologize?
