Does this friends with benefits loves me or just f* buddy?

I I'm in love with my friends with benefits, I'm a gay and he's Straight or maybe bisexual. Sometime he seems like he likes me sometimes he seems shy maybe because he doesn't want to look needy or he dont want me to think or dont want to make it obvious. One day I was walking and I saw him, he followed me in front of the house and pretended he was passing by. That night he is drunk I saw him and I hold he's back, we make it again then I kissed him on the cheeks but he pushed me away, something happened that night but now this is the first time he stayed overnight. I hugged him untill 4 am until he woke up, he pretend to ask what time it was, but he was shy to look me in the eye, like he does when he's sober. I know he doesn't have girlfriend. I hugged him and said thank you, but he didn't hug me back because he was sober and he hate expressing he's feelings. Every time I saw him I call his name so as not to look awkward what happen last night. I passed in front of him one night and I stroked he's hair once and then I left. The next morning I was blocked on FB and then his account was in private but why? So I packed my stuff and went away to my sisters house to give him space. After 2 weeks I came home and I saw him sitting on their front door I pretend that I'm already move on and pretend I didn't see him in any place. The next morning I was singing on the front door and he heard me singing because he's on our neighborhood then he is shouting saying "your great with bad words" but I kept singing like I don't care, after a while he walk infront of me and when he's bit far away he shout a bad words. after 3 days he's drunk and I hear he's playing he's loud music like the song I used to play with him, and the second song is " I wish this Christmas you still remember me, To see you again to be with you again". Maybe that song is for he's ex , I don't know, Im confuse I wish I'm the one he's playing about? But I want to know if he likes me too.
