I'm think a boy from a nother class in my school likes me but I like a nother guy. What should I do?

The boy i like is in my class and he sometimes tries to talk to me, he sometimes makes eye contact with me and he tries to touch me if he has the opportunity to. For an example shaking my hand, bumping into me, taking something from me then giving it back (trying to touch my hand while doing that). I think he likes me and i like him too. But there's this other boy from a nother class that i think likes me. One time when we were on a two day field trip the first day he was stealing my hat on the bus, he was wearing it, he would stand when he wasn't supposed to, he was just very outgoing. On the second day he just sat in his seat and looked at me the whole time. Also a cuple of days ago he added me on snapchat and he is sending just black picks with the time on them. I don't know how to feel rn. If someone could tell me some tips i would really appreciate it.

Ps. My crush wasn't on that field trip.(if that helps with anything)
