Well... I'm not a mental health professional. So, at the risk of stating the obvious, I'll just suggest that the answer may be marriage counseling. (Hopefully some other members, here on PC will have some other suggestions.) In the meantime, however, here are links to some articles, from PsychCentral's archives, on the subject of marital communications. Perhaps some of the information in these articles can be of some help:
