confused about guys

So there is this guy at my church that I like and today everyone was in a circle and I was next to him and so my youth pastor told everyone to put our arms around each other and so we put our arms around each other and then I said that my arms were hurting and so he started messing with me like he was pulling on my arm and so I did it back and we just kept doing that and then since he had his sprite bottle in his hand And so he accidentally hit me in the boob and so how do I get to talk to him without him knowing that I like him!!!!
