I don't know what to think, should I confess or not?

Ok, well...it all started in class. I promised my best friend that I was going to confess to the guy I like at the end of the year and now that it is the end of the year, I couldn't say it (i am a scaredy cat). So my best friend persistently pesters me into telling him my feelings and I really didn't want so I said she could do it. As she happily walks towards him, I ran to the teacher, asked to go to the bathroom and ran as fast as my legs took me. About halfway down the hallway, I felt faint and anger towards myself because every time I like someone, I always avoid them. I know I shouldn't but I can't help it. Anyway, when I got back to class, 10 minutes later, one of my friends (let's call her FRIEND A) was talking to my crush, getting info for me and one of his friends (aka Boy B) yelled, "He likes a girl that isn't smart!". I hung out with the teacher for a bit, then walked back to my friends and caught up on the details I missed. FRIEND A stopped my best friend from telling my crush that I like him since he would wonder why I didn't say it to him instead of my friends. FRIEND A tells me that my crush likes girls that don't change (which might be me, i'm still really childish) and he also said I had a pretty face and that I was really innocent like an innocent angel (those were his exact words) and that he like my attitude (i'm really helpful and I can't say no to anyone). I really don't know what to think, what does all of this mean? We were in the same drama class and were in a couple of plays together, one was called the Kissing Booth play and he had to hold my hand and kneel as if he was proposing to me and that was when I started to like him. And then there was the play before that when we had to play husband and wife, it was so much fun and I started to develop feelings for him. On our last day of drama class, we had free time and danced for about an hour and my friends said he was staring at me the whole time. I always thought he did, but I was never sure. During my monologue, he was staring at me intensely (quoted by my friends) and whenever I aced my test, he would say, "Good job!" I love the way he talks, he's not really popular and is really similar to a nerd but I really like him because of his attitude, not the way he looks. So should I confess or not?
