"Then when SIL turned the corner into WIFE's line of sight, the mask INSTANTLY went on, and she switched from scowling and brooding looking to bubbly happy and being overly nice to SIL who she outwardly hated for years. "
This is natural human social behavior. How many times have you been in argument with your W or GF on the way some where, to a get together, then you get out of the car and you both turn on the "so happy to be here" routine?
The real question is why were you so focused on her that day? It appears you were staring at her through the window like a puppy dog waiting for master to come home.
Next time pickup time happens like that, resolve to not even look out the window. VOW to yourself not to care about her, how she looks, what her demeanor is, whether loser OM is with her, what they are driving, etc.
Whether or not you want to admit it, you are still way too attached. And until you admit that to yourself I don't see you making progress. ACTION, not words. You type how you don't care a lot on here, but what are you DOING (like not watching her like a hawk through the window at pickup) to BE detached??
Ok I will brace for your response in case this hit a nerve....
