Your wife clearly knows how to accurately read people. It is good to have a partner like that because you can always rely on their opinion about important subjects.

If I were you, I will hold your wife's opinion in high regard, not everyone can manage to accurately read people, especially because there will always be a lot of deceivers who thrive thanks to their falseness. Identifying them can help us a lot when choosing people to form relationships. Sometimes, good moments can blind us and stop us from seeing the true face of a person, but eventually every mask fades and the truth is revealed.

Of course, when we realized we were mistaken about someone it might feel as a punch in the gut, but this can be seen as a life lesson, and it allows our wisdom to get bigger, so next time, we will know what to do, and know how to interpret subtle signals.

Cheers!
