I have never ever heard a man say, about another man who was cheated on by his wife: well, he seemed so aloof, and his wife is an outgoing girl, so...
When a woman cheats, men can’t come up with any explanation besides, she’s a hoe and she belongs to the streets. When a man cheats, everyone wants to bring out the scales of justice and start weighing his cheating against how many hot meals he didn’t get, how many times she wore a bonnet to bed, how many times she didn’t laugh at one of his jokes, etc. As
@Crackers Phinn stated above, “girl code”, is to offer additional balance and support in the face of this.
