I'm going to cut off a friend I found out was abusing his gf
How would you know he abuses his girlfriend. Are you a witness?
I found out recently he beats his girlfriend. I also remember a time when he hurt my feelings.
You should hold abusive people to a moral standard and reject their behavior. Nobody deserves to be abused by someone and you should not be expected to hang out with them.
He didn't abuse me though. It's not abusive if it's gay love. He didn't hit me in the face, he just slapped me in the dick.
Even if you don't think it was abuse towards you, if he abused other people it is okay to not want to be around them. You should have people that meet your moral standard around so that you can feel good about being around them.
