I agree with KML. That is one possibility. Another angle to consider is a need for control.
MLCers have a mind that's racing 100 miles per hour because they are trying to make sense of all the garbage spinning in their head.
It's possible there is some element in your W's existence that's beyond her control right now (work, family, finances, etc.) She may be trying to compensate by trying to control you...or give her the sense that she is.
Just remember to STFU and let her ramble. I am doing great at that now. The more I keep my calm and remain quiet - the more my XW rambles. They reveal more than they intend to.
