i let my crush know i like them

ok so there's this guy jacob and we're kinda close friends but i've had these feelings for him since forever. he never seems to notice me the way i wanna be noticed, which is frustrating but also kind of makes me feel special because no one else cares about him as much as i do. anyway, last week at a party his friend was talking loud and i could see jacob kinda cringing. so i walked up and whispered something like 'is he bothering you' and my heart was racing because even though we're friends it felt like more of a moment than just a random interaction. then i got super bold and told him that if he needs an escape from someone annoying he can come talk to me anytime, as in literally anytime, not just at parties or whatever. after that the friend left us alone and jacob kinda smiled at me but didn't say much more. i felt both awesome for doing something about my feelings and also scared because now i feel like everyone will know how i feel about him. so here's what happened and you tell me: am i just being paranoid or did he actually get that i meant it? also, should i keep pushing this or let things develop naturally?
