question: my husband has been acting different lately. he told me he is not tired of being married but he is not happy. he can not tell me why he is unhappy, he just says he does not know. could he be suffering from a mild case of depression? he had a stroke 4 years ago, could that lead to some sort of depression now? he has not been eating much lately, is distant, and has trouble sleeping good ( but he works graveyard shift). any advise would greatly be appreciated. I don t want my marriage to end over this.
