My guess (not stated in article) is that a man is much more likely to want to keep his wife happy and the marriage together because of the financial hit he's going to take in divorce court. Since women usually benefit from divorce court, where's the incentive to work on the marriage if your literally going to get richer from divorcing the man you cheated on.
