Need help with a girl...

At a summer camp, I met a girl (age 14) when I was 14; we live about an hour apart. She kept looking at me, and since she wasn't bad-looking, I started to like her. It was pretty obvious that she liked me. A friend told me he saw her write my name on her arm, with a heart. I did the same thing, and it went over well. On the last night, there was a night hike for the older kids, where we held hands. After that and when we were leaving, we hugged twice. We exchanged a few messages on Instagram, and I sent her a couple of Reels related to camps and stuff like that. One of them was about going to camp with someone again. She agreed that it was a good idea. Otherwise, she responded with emojis. I like to respond to messages from other people with a double-tap (=heart). After I did that, I got a voice message from one of her friends through her account asking if I had a crush on her—which wouldn’t be a big deal—or why I would do that. I apologized and said I did it without any deeper meaning. She read the apology but didn’t reply. Two hours later, she wrote that she was blocking me. I replied, “I’m fine.” Then she wrote, “Everything’s fine,” “I’m not blocking you,” and I asked what was going on, to which she didn’t respond.

What should I do?
