Slowly we unfurl, as lotus flowers

Keep in good relations with your MIL. The more people on your side of "reason" the better, especially if the are on the W's side of the family.

The other thing that is tough about her is she bottles up her feelings. She did this in our M, it was part of our problem. I never realized how much some of the things I did hurt her because she never told me. So now, with that same trend, she doesn’t open up now either. With anger or anything else. …

All too familar with this behavior.
Definately not a good thing, It only builds resentment.

This makes it tough to have any idea what she might be thinking

Don't try to mind read if it's about the R.
If it is about your D2 then feel free to ask her.
