How do i be less shy

Hi so I don't want to tell any of my friends this because they're just going to be annoying about it and piss me off. So this all started last year when this guy followed me on instagram. We found out we had so much in common together and share the same interests. We started talking and sending each other reels everyday. But the thing is, we don't talk irl 💔💔 I've haven't spoken a single word to this dude in person. He does want to talk at school, but I'm too shy to even make eye contact with him. I avoid him but I DON'T MEAN TO. Idk how to not get nervous when he's near me. I feel really bad becuz I act so talkative and extroverted in text but can't even say hi to him in person 😭😭😭😭😭😭 I hatw myself
