Good lord just let him love you or let him move on, and I mean that the nicest way possible, but from experience if he has genuine feelings for you and you're doing this? It's gotta hurt way more than he lets on, he WANTS TO BE WITH YOU, and you push him away, he clearly has presence of mind to think of you, and then want to to start a relationship, and he's put up with it for a whole year, I promise you someone who wants something from you and just wants to bang would not put up with you for this long, so get it together and give him your best, or let him find someone who will, I say that a bit harsh in the hopes it gives you the push you need one way or the other, but for real, mixed messages hurt when you really care
