My MIL understands a bit more what my wife is going through. She was sexually abused as a child and suffered from depression when my wife was growing. She understands that she has a lot to do with my wife's childhood issues. Her whole family knows that my wife has issues that she needs to deal with and they get frustrated.

MIL knows what it's like to have depression color your thoughts and actions so she's totally convinced that my wife's feelings for me will return when she gets through this.
