If your husband is loving, caring and adjustable then where is the confusion?! Just talk to him about your worries and concern about their over involvement in your personal life. Any caring husband will think sensibly on the issue. If he does not cooperate then you have to develop an attitude to ignore them in certain interferences. Do not worry about what will happen when your son grows old because they will also grow old and weak. At the same time you need to respect them and involve them in certain important decision of your life. Their experience and attachment for their son will also be helpful in your life.
