My oldest some was not spying. They have Life360 which allows the family to track movements and how fast they drive etc..... I told him to not worry about where she goes and that I’m fine with it. Many families use the app. I have them also so I can track my sons in case of emergency. It gives a lot of information My wife obviously forgot to turn off her location and he happened to see it. He uses it to track all his friends.
As for me I know I need to let go emotionally before I file. I’m slowly getting there.
