Will a cheating wife/husband get whats coming to them in the end?
I don’t know about cheating husbands, but cheating wives do get rewarded with Alimony once they add insult to injury by divorcing their cuckold husbands. So I don’t think karma helps men much here. It is said that God helps those who help themselves. So the best course of action is not to get married in the first place. Remember, don’t sign fraudalent contracts! No-fault Marriage is one such contract.
