i definitely think that affairs are bad news, but if he's so unhappy with his wife why not just leave her? i agree with what was said earlier, that life is too short to be in misery. talk to this guy, tell him that perhaps an affair would not be the best option, but that you're there to offer support should he decide to divorce his wife. if she's pulling the "but you can't leave me i'll kill myself etc" stuff to make him stay, tell him to get her ass in thearapy then file for divorce. i understand that they probably loved each other once upon a time but they shouldn't be trying to stay together just for the sake of nostaliga. good luck
