Does this mean he likes me?

Theres this guy I've liked for a year and lately he's been doing things that kinda make me wonder if he likes me back, but I'm not completely sure because he's kinda flirty. So anyway last night we had this monthly get together at someone's house and i was sitting in the living room with my friend and he came in late and peeked in the living room and he waved and smiled at a person next to me and he smiled at me too, once and then he made goofy face and I thought maybe he was doing it at the girl next to me because we barely talk except for these get togethers but he was looking straight at me so I smiled and looked away. And we were looking through videos on my friend's ipad and my other friend recorded herself on it so I jokingly said "ew delete it!" and he laughed way harder than he should've bc they have a history and he thinks she's nuts. Later he was talking to my sister and he or she brought up the fact that I only talk to him here even though we go to church together every week and he began to list all the people I talk to except for him. I never talk to him cause he always seems too busy with his friends and girls drooling over him but apparently he wants me to come up to him even when he's with his friends. Sometimes I flirt with him and vice versa and there's other things he's done in the past but like I said he's a flirt so I didnt take it seriously. So does he like me or is he maybe starting to? Thanks!
Added (1). And I dont want to ask any of my friends about it cause they all like him and my one friend still isnt over him so i try not to talk about it. Also he never responds to my texts or snapchats but he always talks to me in person and always makes sure he hugs me.
