I would really appreciate your guidance, as I could use some advice at this stage in my life.

I'm feeling a bit lost regarding a relationship situation, and I could really use some advice. Here’s the story: back in December 2022, at a classmate's birthday party, my best friend and I met his older sister, who is two years my senior. I remember thinking she was stunning and possibly the most amazing girl I’ve ever encountered. I developed a bit of a crush on her, though it didn't feel intense enough to be love at the time. We played tag and had a great time, and afterward, my best friend shared her Discord with me, which led to a group chat that eventually became direct messages. Fast forward to the following year, I'm now at her school with my friend group. The school divides grades for lunch, so we only see each other for about an hour each day, but that little time still makes me happy. Over months, my crush deepened, and I fell in love with her. My social media feed became filled with thoughts of her, and I almost mustered the courage to confess my feelings daily. However, I felt self-conscious—at 5'1" and with an awkward hairstyle, I knew she looked far more put together. Finally, I decided to tell her how I felt. While in my gaming setup, I had a little chat with her on Discord, then revealed my feelings. She kindly said she didn't feel the same way but wanted to remain friends. I was so embarrassed that I suggested we shouldn’t talk anymore. Ironically, we had to sit next to each other in class, making things exceedingly awkward. I avoided eye contact and didn't speak to her for the rest of the year. Now, two years later, we’ve started talking again, but not in the way you might expect. She transferred to another school, and most of our conversations now turn into long-winded arguments on Discord, often about her little brother’s disdain for me. Interestingly, my best friend—her brother—has also distanced himself from me for reasons I still don’t fully understand. As my last year at my school approached and I prepared to join her at her new school, our friendship improved, and we began chatting a lot on Instagram. During winter break, out of the blue, she confessed that she liked me. I was overjoyed, especially because I had just found faith in Christ, which felt like a beautiful gift. This was one of the happiest moments of my life since I was still deeply in love with her. However, after we returned to school, our communication waned, and I found myself waiting for her to message me first. Unfortunately, that rarely happened. A month after winter break, I made a regrettable joke about her little brother, which led her to block me. She has a history of blocking me over trivial things, often alternating between blocking and unblocking over the span of weeks or months. Despite our Instagram fallout, she didn’t block me on Discord. For two days, I messaged her every 30 minutes, but she mostly ignored me until she eventually replied that her notifications were off. While I found that amusing—calling her on Discord rang through—I felt she was being particularly unresponsive. She did unblock me on Instagram, but when I tried sending her a bunch of reels, she just left me on read, which left me feeling really down. When she blocked me again shortly after I sent her a reel on my way home, I started to suspect her little brother might be influencing her decisions. Now, she hasn't unblocked me or responded to my messages on Discord, and I’m unsure what to do next. I’d appreciate any advice from you all. Thank you, and God bless you! Edit: Just to clarify, we won’t be able to date until I join her school, and her family is not fond of me due to her little brother’s negative comments.
