I also wanted to tell you that your W could be suffering from other things that has caused her to be very depressed and that adds strain to the MR.
Can you tell us if she showed any of the similar signs when she was pregnant with the first child?
I know that losing a job can feel very scary when you have a family to support. It is good you have parents who can give you a place to stay, but I also know what that can do to you personally....and to your MR. I hope that you can find a job and are able to move out soon.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
