Hi, I'm 32 year old married man. I got married about four year ago and it was an arranged marriage. Now I am hopeless due to hyper behavior of my wife. Whenever I deny something to my wife or try to make her understand something, a long argument take place and if I am not agree with her than she becomes hyper and at last she behaves like insane. Try to leave the home immediately or try to harm herself by taking the knife at her throat (even on throat of my 2.5 year old son). She had also tried to jump from the running car (with son) ones time because she was scolded her for some expensive purchase. But just after half an hour she becomes normal and accepts her insane behavior was wrong. She also accepts her fault in part and complaining a headache just after the incident. Initially I ignored this but throughout time I see repeated pattern. Her some relatives told me that she possess this type of behavior since childhood and her farther and grandmother also have the same pattern. Is this any type of genetically disease? Or psychological problem only. Is there any cure for it? Please suggest me.
