it makes you feel discouraged from trusting people.
After my divorce from my own narcissistic cheating ex, I realized that I didn’t notice the red flags precisely because I DIDN’T grow up with any family dysfunction. I’d had no idea I should be on the lookout for this stuff.
It’s one reason why it’s useful to read up on narcissism and on sociopathy. We want to see the red flags and pay attention to them in future dating. That doesn’t mean we can’t trust again, but we need to give our trust to people who are worthy of it.
