Does he like me, like even a little?

I know, I know, this is a cliched question, but I'm dense and unsure of what I should do. So he was in my cl last year. He liked this girl for the first half but then he stopped liking her. Then at the school awards, we sat next to each other and he saw me the hole in my jeans, out of habit. So when I finally stopped, he poked the skin that was showing, which was my thigh. I squeaked and he realized I was ticklish. He kept tickling me and when it was over I went towards my cl and my friend was like, "You two were so flirting!" And she said my face turned red the second she said that and he kept looking at her and then at me like he was trying to figure out what happened that made me blush. So the last day of jr. high came and everyone cried when our teacher read a book. Including me. He hugged me and he teases me about it now. Over the summer he messaged me on facebook. His message started with, "Hey y." I thought maybe he made a mistake but said hi and continued the convo, eventually he started flirting. We stopped talking over the summer and then we finally saw each other at this big party thing. It had like a stage and a bunch of seats. Me and my friends were in the front row and he stole my seat when I stood up so I had to sit in his lap. He instantly wrapped his arms around my waist and would groan every time we had to stand up. And he'd keep his hands on my waist. At some point he would link his fingers with mine and kinda rub his thumb against my hand. He was like, "I'm a bit sleepy... so if I fall asleep don't be worried..." And he kept shifting a bit and laying his head on my shoulder trying to sleep and he'd mumble things into my ear and stuff... I know it's probably dead obvious if he likes me. If not, I'm super confused. And I'm not sure if he's a consistant flirt or not.... but all I know is that night I was the only girl he interacted with the most. A few times he'd talk to one of my female friends. But I don't know. Someone please give me advice?
