If you are a victim of assholes, and it's happened more than once, it's time to get therapy to discuss codependency issues and how to reestablish boundaries. Even with a psychopath or narcissist, it takes two to tango, and one's lack of boundaries allowed the poor treatment. The scary part is that anyone can create a monster out of an otherwise halfway normal person by not establishing boundaries. I've been on both sides, and it's eye opening that ones character is so fragile even when we think we're good people who would never do such things.
Nobody is immune. Never forget to check yourself. If your spouse says they feel like they are walking on eggshells, then spend some time in cognitive silence to evaluate that severe red flag and if you're projecting your shit onto someone else. It's an easier mistake to make than you think, and it is easy to do abusive behavior without knowing it.
