Could this teacher have a crush on me?

He was my art teacher last semester since the first day of school. He’s probably around at his 40’s, and he is already married with a daughter. I’m known to have good art skills and he was always impressed with my skills. He’s always nice to me, because I’m usually a quiet person. At one time, we were painting our landscapes; a student next to me was asking him for help so he sat on her seat and did some help for her. I was trying to dip my paintbrush onto a cup of water, but unexpectedly, he quickly dipped the paintbrush on it first, and I held my paintbrush back, and I’m certain that I wasn’t showing any reaction. But the students around were looking at me, and the teacher just didn’t say anything and just stared blankly at the paintbrush while mixing the paintbrush on the cup of water. Thinking about this just makes me feel embarrassed. Not only that, but he was also staring at me while I just put one of my legs up on my chair to tie my shoes. This semester, I had him again for ceramics that time. But shortly, I got allergic to clays, so I have to drop off his class. Since then, he kept looking at me whenever we see each other again around the school. And he was also looking at me in the hallway while he was talking to another art teacher. Today, he saw me as he was walking then he turned his head and quickly stare at my back. This is really bugging me, and I think it is really weird to have a teacher crushing on you. I have been trying to avoid him and avoid walking through his classroom. I’m also feeling glad that I’m no longer in his class. But everything about him it’s just scaring me, do you think he does have a crush on me?
