Should I tell him this or no

Should I tell my 3 year FWB “take care of yourself” or something it kinda just ended when I told him I wanted more friendly talks that didn’t revolve around sex and he said excuse me?! I said it’s true you always talk about sex, I’d appreciate more conversation that wasn’t revolved around sex

He never responded back it’s been 12 days I did I unfriend him but curious if I should message him something like well this was fun while it lasted take care of yourself 😊

Should I??

I’ve know him for 21 years for context but I don’t know him know him we have been FWB before on and off this time was our longest being FWB
