My friend A is friends with a really weird and bad person, B. B did awful things to another friend of mine (plus he had gf when he did this, and they are no longer together).
My friend C tried to tell A about how B is talking about B like she’s and object but B didn’t listen or care about what C had to say. B even said that A is changing despite doing weird things to that friend.
I feel like I’m stuck in a situation and I don’t know if I should stop being friends with A. I don’t like B and he makes me feel uncomfortable, not to mention my own significant other doesn’t like B either because of the weird stuff he did.
I’ve known A for a long time but it’s getting harder to keep A happy and it’d draining, what should I do?
