He doesn't listen to anybody and sometime explosive or depressed. He has had always labile emotional character. in earlier life he was anoid with his parents and brothers for not giving him proper respect and dominance that he deserved and now he is doing same thing with his sons and wife. he thinks he is always right and every decision should be asked from him. but he himself has been a very poor decision maker. he is used to be abusive on very ordinary situations. now he thinks that his sons has used him as they are grown up and do not give him proper respect. he does not talk to us . what should we do
Hope you can cope
My first suggestion is for you to get some counselling. It sounds like you were raised in a dysfunctional family, or perhaps by a narcissistic parent, and you could use some support.
Maybe what you should do about his not talking to you is be glad. You cannot control his behavior. You can control yours. Send him an occasional greeting card. Visit him occasionally and if he isn't talking to you, fine, visit with his wife (your mother?) Do reasonable things that respectful sons do (counselor can help you understand that -- I'm afraid your father's idea of respectful is warped) and hold your head up. If he chooses to shut himself off from his family, that is his problem.
BUT ... it would be helpful to know more about this situation. What is his diagnosis? Do you live with him? What kind of care does he need? How old is he?
