Can someone help me out please?

I see that this guy may like me but we act so weirdly around each other. We don’t talk to each either. Last week, twice he got me staring at him but I got so nervous that I looked away. I think he thought I was avoiding eye contact because the second time he can over put his head back like he was sad. There were other times that he would look over at me too. Most of the time he looks when I’m not looking. I don’t know what’s wrong with me. I’m so scared to let him in because he could be my first boyfriend. I’m just too scared to talk to him. No other guy makes me as nervous as this guy. I don’t want him to think I hate/ don’t like him when I do. My feelings are getting stronger and stronger each day and it’s getting to me. by the way, I see him around church today 😭.
