When I first met my wife she lived in a town far away from her mother. When we got married her mother moved to the town we live in. We actually built our house on her mothers land which was a bad idea. My W even mentioned this to the MC. My W often gets guilted my her mother into doing things she really does not want to do. My W tells me about this and I used to get mad, withdraw...now I don't get mad. I tell my W that I am sorry that her M has done that to her and that my W should not let it ruin her day. That's the only way I know to react to it and the only thing I know to say.
