So this guy I know has sex with this woman while her husband watches. I know there are husbands like that, so that was not the shocking part.

He's showing me some texts he has with the guys wife and he says they go to the same church. He continues on to tell me that because the husband knows its not considered adultery.

I tried to google this but had no success in finding any info on this.

Wondering if anyone here that is into Christianity can tell me if thats true, im just curious if this guys is making it up or not. The guy is single.
