I think cheating these days is pretty “conventional”, sad to say.

If it is your brother/best friend, he should be able to handle the discussion. Not everyone with another clown in the tent is some free thinking open relationship rebel, sometimes, they’re just being shit on by their SO. And if it were me, I’d like to know.
