Was inappropriate with a friend who’s 2 years 1 month younger than me.

I’m 18, I’ve known this friend since I was 16 however. I’ve known him for a while and consider him a good friend so I made inappropriate jokes towards him. I realised that an age gap of that distance was grooming and now I feel awful.

I don’t know what to do I feel so guilty and like a groomer. I’m scared a lot of people would hate me.

Can anyone help me with how I’m feeling?
