You said he's 'bothering' you, imma take it as in you hate him doing that and want him to stop.
If i were you, i'd just to be straight forward and tell him that i'm uncomfortable with his behavior. Guys like that would keep bothering you if you keep being easy (as in, you don't complain and keep quite of his shenanigan)

The thing is he’s my older brother’s friend. I don’t hate him but he’s kinda annoying me now tbh first he gave me chocolate thru my brother then the next day we went to the cinema with my brother and his wife and he kept trying to talk to me and I don’t wanna talk to him cuz it’s just awkward. He kept nudging me and I keep pretending I don’t see him and i was getting uncomfortable cuz i don’t know what he wants. He wouldn’t say anything straight to the point. Oh and i didn’t invite him to the cinema my brother did.
Yall there’s this guy who keeps bothering me in person and literally wants my attention but doesn’t even text or chat me if we’re not together, what does that meannn? Like do guys do that often?
