I love my sister in law. I always have, although at times in the past I was a bit intimdated by her and didn't really feel close to her. Then when my mother died three months ago, she came through for the family. She helped me when I needed someone to and I saw how much she was grieving for my mother. So that really cemented my feelings for her and I value her more than ever as a member of our family.
My sister's ex, loved him dearly and was sorry when they divorced.
Dh's two brothers, can't stand either one of them and thankfully never have to see them since dh can't stand them even more than I can't!
