Does he or doesnt he?

Ok, so I have been friends with this guy for a long time and a few years ago we wnt out, then broke up then a year later he told all my friends he liked him and wanted to go out with me . i rejected him but we are still like best friends. after about a year of not hanging with me, he suddenly shows up. he currently has a gf(not me) but i like him and i told him. he's cool with it but i'm wondering if some of the things he says and does means he likes me too. what do you think?
