Im conflicted

KEY POINTS ARE BOLDED

So basically I like this guy, i only have one period with him but I've started getting feelings for him. We sit next to each other because of our last names and we're partners for the rest of the year (he chose me) for assignments. We always goof off and play 2 player games on his computer. He even grabbed my backpack for me when I was tired and fell asleep (we have to put our backpacks at the front of the class).

Yesterday, I found out, he has a girlfriend. I tried to keep my distance today now that I know but he kept being touchy and I don't know what to do about it cause I dont want to ruin a relationship.

I don't wanna seem like a pick me because I know a lot of the things I listed Just seem like general acts of kindness and friendship but it really seems like more when it's actually happening. I could also just b delulu so lmk
