I had a great MIL. She lived with us after her husband pass away. She stayed out of our business and also did her best to help where we needed her. I have 4 children and she helped raise them while I worked. But when I came home it was my job not hers. My husband was their only child and when we got married both of his parents said I was the daughter they would of picked. I felt the same way too. I really try to be like my mother in law with my childrens spouses.
