I think im loosing my best friend what do i do?

me and this individual were friends since 6th grade, funniest and best friends u can imagine but freshman year things changed. I needed a ride and he said he wud be late to practice, so i was left on the curb and i didnt tlk to him 2-3 days. And he had told my other friend I needed him more than he needed me. I was shocked and he didnt make the school team and he became more of a dick im a sohpmore now and we hang occastionally but its not the same its awkward. He tells me how hes misrable and we were best friends but he seems not to want to hang with me. i guess my question is shud i sop tlkin to him and let him realize our bond or keep making it wrk
