I'll admit, the recent interactions with W have gotten me spun up a little bit. My mom also told me that W keeps contacting her and expressing her pain and love for me.
She knows it will get back to you, because it is your mother. It's under the auspices of confiding in someone she's close to, but W is no dummy. This is strategic. She's got your mother pulled into the game.
W is working very hard on multiple fronts to keep you on the hook so she can avoid feeling emptiness and uncertainty. That's what's happening here. Whether this will progress into something resembling less game playing, we have yet to see.
