The thing about some mother in-laws is that they believe know one will ever be good enough for their sons. It doesn't matter who she is, in your house she should respect you the time that she's in there. If talking to her didn't help and she did the crying bit, then I think you need to say something to her. Your partner should be okay with this though, because this is were "tough love" is going to have to come in. It happened with me and my husband. Everything I did she could do better, critized the way I cooked, she even went as fars as cutting my chidlrens hair withougth permission!!! I had to put my foot down and tell her that she needed to respect me and my house and my choices or she would no longer be welcomed in my house. My husband was okay with this, he loves his mother dearly but he married me and his life was to be with me. She cried and didn't come around for awhile but..14 years later, I have the best relationship with her. I love her like she was my mother.
