What does this mean?

So my brothers friend. We’ve all known him for about 4 to 5 years. He’s one year younger than me. We were in the same high school but we never saw each other. We moved out of that city to another city a few months after I turned 18. Then he still hung out with my brother like a lot. They’d fight like family not talk for a few weeks then he’s back. He is a little monkey my brother always treats him like a little brother when he gets annoying when he’s having fun with him. Random trips to anywhere with him.

Okay so here’s where I a concern for myself. He’s a dorky weirdo whom I see as my little brother, I’m the youngest never had a younger brother so I treat him like that. When he comes over I’m sitting in my car for a little bit listening to music, he says something heyyyy gimmi a hug and I push him over there and I’m like no in a funny voice of course. Every time we see each other he talks to me and I never really look at his face cuz I start to smile and laugh, as does he. I always dodge his hands when he tries to touch me. I tell him to leave me alone, your annoying, you monkey go away but he’s just always consistant. I was listening to music again the other day and he comes up to my window that I had open on the passenger side and scares me and i told him I hate you oh my god I hate you he’s like awwwww I love you too. He came up to me when I was petting my dog and he’s like putting his fists up, and he was gonna lightly tap me like heyyy, what are you up to, how are you, and i pushed his fists rapidly away from me and he’s like damn why so agressive. What the fuck is going on here. Is it just me thinking he has some sort of feeling for me or do you think so too?

I don’t know what to think.....
