Does he like me or just likes flirting?

ok my best guy friend im not sure. ok i sit next to him in homeroom and he always talks to me during cl and last week he started kinda saying gross things. in social studies he asked me if i wanted to be a candidate in his bedroom, and he kept saying all this stuff like wanna come on my ride, but then he'd laugh. and he also texts me when he doesn't text any of my other friends. and he seems to like me but im not sure. and also for halloween he asked me where i was going trick or treating and i told him and he was going a diff. place and he was disappointed. so what do you think? thanks!
