Was he flirting ? boys your opinion!?

A few weeks ago i visited my hometown state after i hadn't seen every1 for a year and my moms best friend with has a really cute son who i grew up with as a kid & he just turned 17 & im 15.. i hung out with him and slept over and he drove me around in his car and let me meet his friends who rly liked me. one night we were sittin on the couch watchin tv when he said get off the couch i wanna lay down and i said no so he said fine and he basically layed down on the couch on top of me (well his head was on my chest), he stayed like that for about 15 minutes...was he flirting? then when him and his friend were playing some game in a room i fell asleep and he scared me and woke me up so i threw something at him and then we started fighting n tackling all over the floor for about 20 minutes and then he kissed me on the cheek when his cousin said 2...was he flirting?
