Dear
Welcome to HCM
We understand your concerns
I went through your details. I can understand. You are saying that there is something wrong about your wife. You are not giving symptoms in relation to your above statement, except anger, aggression, argument with you and lack of sexual life. Anger, aggression and argument with anybody can happen due to extreme
stress. Stress may affect her from anywhere like job place, home etc. As long as the information goes, for the time being a diagnosis is not possible. you may take your wife to a
psychiatrist / psychologist.
In your case, you are going through this ordeal for 8 years and you did not even consult a physician regarding this? You should
consult a psychologist soon, for the better of your whole family.
