Guys do you think i've messed up?

He clearly showed signs he liked me..then he started doing a lottery syndicate with my mum. So he used to come at the end of the week to check the winnings. I was fed up of not doing anything..so i thought if i text him some lotto numbers from my mums phone obviously with permission and my name at the bottom of the text. He didn't respond to my text..but he did ring my mums number asking about some other ticket the next day. So i was waiting for him to come at the end of the week...he didn't turn up. Is he avoiding me, guys do why would you do this to a girl. He clearly showed he like me. Whats wrong with me...or he doesnt like me ?
