i think im crushing but idk if its a good thing

so about three weeks ago, i (21FTM) got out of a relationship of a year and a half with my ex (20M, whom of which is now a good friend of mine). the breakup was sad, but for the most part, we are both pretty happy with the decision because we want different things in life and we just generally don't work as a couple. with that being said, i have another friend (20M) who i have a pretty extensive history with. we've dated a couple times, and we were in a situationship the last time we were involved. i hung out with this friend the other day to watch a movie, and we both know that there are some unresolved feelings on both sides. throughout the movie he kept moving closer to me, and i could tell that he was doing it on purpose. it made me nervous, but in a good way.. we ended up cuddling after the movie, and we talked about our intentions with each other, and we said that we would take things slow and that we're just friends who cuddle sometimes right now. since i left his house that night, i havent been able to stop thinking about him. i know its a crush, i kinda never lost feelings for him, its just that time away from him made those feelings dull out. what im worried about is, am i a bad person for doing this right after me and my ex broke up? and is it weird that im already starting to think about my friend non stop after one cuddle sesh? please give me some advice cuz idrk what to do or think.
