How Do You Screen For High Value Behavior, When Women Are So Good at Concealing Intentions?

In my life, I have experienced moments of high SMV and low SMV. The difference was astounding. The same women who was doing me favours, simping, etc. turned out to be a low-value bully when my SMV dropped.

My question is: How do you screen for high value behaviours when you have high SMV? I try to watch how she treats those below her, how she treats those who she doesn't need, how she talks about other people, etc. I try to listen to her rationale and watch her actions rather than what she says. I watch how she holds herself and her frame.

Any advice?
