Do you and her exchange pictures often or is that new?
Or is the talking of the kids growing up so fast the new behaviour?
For me, aside from S17’s grad, W has not asked for, taken, or shared any pictures with me or the kids.
Like your W, she is going to wonder where the time went.
I do believe that MLCers are living in their past. The behaviour, clothes, mannerisms all point to their younger selves. Once in a while they float back to the present for a brief time, and I suspect feel a lot like rip van winkle. This of course leads to more confusion and stress and off they go again.
As you know, just let W do what she has to do.
Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
