He rested his arm against mine?

I was sitting next to my crush in the computer lab.

It started with him brushing his elbow on my elbow, and then he just rested it there.

Is he attracted to me? Was he aware? Am i overthinking it?

Obviously this isn't the only sign he's given me but if I were to go through all of my interactions with him then I might as well write a novel. Just base my question off of attraction. If a guy does that is he okay with touching me?
