He stayed friends with Doug. Letting your friends fuck your wife is one thing, I mean if it was good enough for Jerry Falwell, it's good enough for Flaming Brian. But to stand by a man who helped you turn a little hobby into an actual career and you became actual friends with? That's just the worst thing possible.What could Brad have possibly done that was worse than that?
This whole story just reeks of high school bullshit. These people are supposed to be adults in their 30's. You know, career is more or less settled, you're in a relationship with somebody, you're saving up for your future and all that. Who Brad chooses as his friends shouldn't be an issue with the rest of his friends. Just make sure never to invite them all to the same gathering and everybody should be fine.
