Should i just confront him?

i like a guy (whos 15) and i (im 14) used to think he liked me. i would always catch him staring at me he used to talk to me all the time. (we would usually text more than talk because we go to different schools but i see him once a week...we cant talk though because hes coaching my brothers wrestling team when i do see him..and my dad is there and hes weird about that stuff) when we first talked to him we talked for two hours. and then he went on vacation and we talked everyday and all day when he was there. when he came back he just stopped talking to me. he never responds to my texts. i still do catch him staring at me and when they play sharks and minnows at the end he always does rolls and shows off right in front of me. im going crazy. i dont know what to do. should i confront him. i was gonna ask him out too. :( y well before all of this.) and i asked if he was mad at me and he said no so idk. plz help me. thanks.
