Why is he ignoring me now?!? HELP!?

Okay so a while back i added this guy on facebook, and i recently told him to "comment my new default"! Than he said "aight, get at mine"! So i wanted to make small talk, so i started flirting asking if i knew him from anywhere and he was flirting back! He said i looked really bomb & that i should talk to him more! So i gave him my number, BUT HE NEVER TEXTED. Than i sent a message saying "heyyy, wussupp! you never texted me hun!" thenn he never replied? So day later i commtented his photo's saying cuteness & stuff & he liked the comments & stuff. So then i wrote a wallpost but he deleted it? Then i tried chatting him but he wouldn't reply? IM HELPLESS. what do i do! I DON'T WANNA SEE CLINGLY! but his soooo cute & seems cool, i just DUNNO whats happening.
