Search Results: signs a guy likes you laugh

Alright well, this guy in my class is mute. He doesn't speak.
Last year, I befriended him by asking if I could borrow a pencil from him. Ever since then, we've been exchanging little notes and I often make silly jokes during class (that was an unintentional rhyme) and he laughs at them, so I somewhat know what his voice sounds like.
A few months ago, through a text, he told me I was one of his three friends, which was kind of surprising to me. We haven't really established that we're (official) friends so it was weird to see that he considered me a friend (?) I'm thinking too much. :/
Sometimes he puts his arm over my shoulder, pinches my cheek, pats my head, clamps a hand over my mouth if I'm talking too much, little things. A few times he has even winked at me. I didn't think anything of it until last week.
I was at his house playing video games with him (I seldom go to his house). He had to go to the bathroom (he knows sign language [self explanatory]) so I was there and his brother came into the kitchen, which is across the way from the living room. While he was grabbing something to drink, he said something like "are you two together yet?"
I was confused and asked what he talking about.
He told me that Jason, which is his name, is always bringing me up during conversations. He also said that he thinks Jason likes me.
I thought it was hilarious at the time. Just the thought of Jason conversing is unimaginable still, and he had never shown any interest in me that way... ever?
We're just friends and I'm very happy with how things are moving along. It's obvious that Jason sort of broke out of his shell while he's around me, but that happens with every friendship.
Another thing to note is that Jason told me that he's asexual. So... I really don't know.
If you need more context, I'll be happy to provide it below in the comments. Thanks.
