My sis-in-law has never said anything to me about my husband and when she is in his presence she tip-toes around him, what she says, how she acts, it's like she is on edge, almost shaking inside. I watch her become extremely nervous around him. One time she stayed with me when my husband left town and she asked me why my husband doesn't like her and I told her I didn't know and she would have to ask him. That was about 7 years ago. I don't think she ever did. When she talks about him (which is rare) she usually speaks highly of him.

The rocky relationship was between my brother and my sis-in-in law. My husband really likes my brother but said he can't get close to him because of his wife (who is my sis-in-law)
