struggling a lot, please answer x

i have this chemistry teacher, and he is acting weird. this is the second year (in a row) he’s my teacher and last year it was all fine. he is so funny, and i was the girl laughing so hard at his silly jokes. he was, and still is my fav teacher of all times. so this is what happened;

i noticed him acting a little weird. just as little as it could be normal. i thought about it and just moved on, with him acting weird in the back of my head. one day i was a little late so i had to sit in front of his desk. he told me he liked it when i’d sit there. and from that moment, i sit in front of his desk. we chitchat every once in a while and thats fine. i noticed myself liking him a little. i pushed it away, but still thought about him a lot. a week of 2 ago he told me he needed a babysitter, and asked me if i’d like to babysit his children. i told him i would, and i am waiting for him to call me! he is still acting weird, like looking at me but he is not a pedophile!!!!!!!!!! he is not! i am 100% sure about that.

Is this weird? idk maybe its me because i somehow like him a little. please answer x
