My wife having so much anger on my mother. Always she thinks about children. She thinks my mother separate children from her even though my parents are not staying with us. My father age is 75 years and my mother age is 69 years. My parents are very cool and no one from relatives or know people dislike on them except my Wife. She always this abnormal about my parents and she behaves almost same with her parents as well. I am only one son to my parents. Please advise what will be the best solution for her.
