Hi T2, I also have a lot of support from my MIL. She can't understand why W is acting the way she is. She is still trying to be supportive of her D which is only natural but thinks that she is making a huge mistake. My D14 stayed with her most of last week (my W's week with her) and D told me MIL cries after talking to W on the phone almost every night. It would be interesting to know what my W is saying that makes MIL cry but that's not my sandbox. I also have gotten much support from her mom's side of the family. I'm hoping that this will last as who knows what W may say if she starts to feel like she isn't getting the support she wants from them.
I have chosen to remain close with MIL and that side of W's family and they want me to as well. I can only hope that my W starts to listen to them if she starts to come out of her MLC someday. Right now she just dismisses anyone who doesn't just agree that she is doing what is "right" for her.
