This girl (18F) is making me (19M) want to be more than friends.

So, I have a cousin on my dad's side, and I "met" this girl at her house when I was 14-15 as she's a friend of my cousin. She found me cute then and hid until I left, fast forward 3 years later she adds me on social media wondering why my name is familiar. We've been friends since July 2024. And we've been talking a lot everyday since then. I love across the US from her now, but in that short time we have developed a close bond, exchanged trauma stories, joke around a lot, call, and it's concerning as Im realizing I'm developing feelings. She alone is the reason I converted from atheist to Christian and has the purest heart. And over the last few days realized I'm feeling more than just a crush and idk what to do, I don't want to ruin our friendship or accidentally scare her away. I feel like she's hinted at having similar feelings, late at night we were texting as usual, and she said she would probably still hide if we crossed paths at my cousins house again, there's been other hunts but idk if they actually are. As you can see I'm overthinking and giving myself hope. like she is becoming a very important person in my life and I don't want to ruin this because of unwanted feelings. I will admit that I'm scared. I've been in relationships before but I still haven't felt like this before. Nothing this intense or worrysome. How do I manage this without risking this friendship ?
