While I do not condone infidelity, I feel that he clearly wasn't getting what he wanted from his wife. You need to have the communication rolling if you want the marriage to survive. Of course husband and wife should put everything they got to keep a marriage intact. My older sister recently had to divorce her husband. It was arranged marriage and the husband was missing a few marbles up there. People divorce for myriad reasons anyway. Happens all the time. She got some good deals out of her divorce, I must say.
