First, glad you took the advice not to send the letters. I think it's good for you to write them but don't send them. Keep them for your own personal growth. Letters rarely have any effect on inlaws.
This is a long process, She said she wanted this wrapped up by the new year. The WAW says a lot of things. The reality is that it will take time.
