Dealing with crush on an authority figure?

i’ve had a crush on this person for about 4 months now i think but yesterday some interesting things happened. so it’s a professor, i came to his class yesterday and he was speaking with a bunch of students very close to the door so when i came in through the door he was surprised. which ok normal response i guess BUT i would’ve dismissed it if he didn’t also stumble his words when he said hey to me.

Also side note i remember last class he was speaking about something then he said divorce and looked directly at me ( i may be delusional about this one) but class went by as normal i stayed back to speak with him about textbooks. i tried to leave because there were so many students but then he asked if i had a question. at a point it was just me and a girl. i asked my question but i clearly wasn’t done then he asked the girl if she had a question and she kept insisting that she didn’t want to say it in front of people then he told her that im ok i don’t judge. they were speaking and at some point he told her he's had many students but he’ll never forget me then he quickly said and you too.

so she left and then it was just us then we spoke about random things, he owes me chocolate so we spoke about that and almost the whole time he had his hands in his pocket. I went closer to show him the brand of chocolate i wanted then i saw something down there but i couldn’t tell if it was his jeans fabric being bunched up or I don't know. oh and also last class again i was walking past him and through the corner of my eye it felt like he looked me up and down. so yea I don't know
