Is he interested or playing games?

Half way through high school,i get to be friends with a guy I'd hardly ever noticed or had paid that much attention to...he's the rich boy snob kind!From the start,he was irritating and we'd practically fight alot to the point tht we'd gotten so comfortable round each other and ended up being friends.So then we start flirting and by the end of my senior yr in high school,we'd kinda gotten involved and I was so totally enjoyin it till it reached to a point where we couldn't get enough of each other.We went our separate ways after a minor misunderstanding and that was what I thought as the end of my best fling ever.Joining university,I get 2 meet him again on my 20th bday and sme way or other we ended up together getting high on red wine,next thing I know,we're kissing more intently than the first time and he so didn't want to stop or let me go 4 that matter.Right after that,we solved our issues and became pals again.So what I don't get is whether he's interested in me-cz we've bn playing the same game 4 so long-or is he just after wht he cnt have or ever get....it's so confusing???
