Crush on the wrong guy!! help!!

i really like this older guy and weve hooked up and done stuff but i feel like it will ruin shit between me and some of my friends since he has drama with them from before The guy is also a really big fboy and has gotten with every girl i know. Me and the guy are very close friends but i always kinda liked him but since weve hooked up ive started liking him alot more. I dont know what to do if i should tell him how i feel, if i should stop talking to him (whixh will be hard) continue to hu with him without admitting feelings (which would be fun) or continue being friends with him and hope the feelings go away (hes also a bad person which makes him hotter to me ahd really wants to do shit w me)
