Does he like me or is he using her to get to me????PLEASE ANSWER!?

okay. so there was this guy named mike at my neighbor declans house. sarah and i were outside with them just like talking and stuff. then sarah went in. mike, declan and i were all playing basketball then. (i play bball) and mike goes, "man this babe can shoot!" then declan punts the ball far and mike goes to get it. while mike is running declan asks me if i like mike. i told him "idk" then we went inside to watch a movie and mike "hurt" his back and had to sit to the chair that was next to me because it reclined. then i was playing declans drums and mike starts asking me just like questions like "do u play? or play piano" and stuff like that. so i went home and was texting him, and he says lets play truth or dare. I say okay. and we were playing and then he randomly goes, "wow you are so hot" then i told him this playfully, "last night i tried to kill the hottest person alive, but suicides a crime." and he laughed. BUT...............the next day he goes "does sarah like me?" i said "idk y?" and he goes "cuz i like her" but the thing is she was only out there for at the most 10minutes with us. so pleasseeeee answer!!!! (if u read the whole entire thing, you deserve a cookie!!!)
