My bff, while I love her to death, has some pretty twisted ideas about marriage. Her husband cheated on her a few years ago and she forgave him, took him back, and moved on happily, but then she found out last week that he's cheating on her again. Her new plan, rather than talking to him about it, forgiving or divorcing him, etc., is to find a man to cheat on him with as revenge. She says that it's okay if she does because her dh cheated first.
Do you think cheating is ever justified?
