How do I let her know they miss her when she thinks I am manipulating that?
You don't. Whatever you would say, she'd take it as manipulation. You let the kids tell her. Do the older ones have her phone number and does she allow them to call her whenever they want, or has she given them a window in which they can place calls to her? My heart really goes out to your babies.
Turning her attention away from her children is a trait of WAW's. She's different now.
So, are you going to finance her new place? If so, why?
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!
