If so, what do they look like? Or rather, at what point is it as good as it gets? (when one gets oneitis? Haha but seriously)

TBH I've never actually seen a truly emotionally stable woman. If we want to talk red flags, they exist in pretty much every woman at varying levels. Lies, psychopathy, manipulation, and confabulation are not only ubiquitous but assured. In that case, are there blue flags indicating positive traits? If so, what do those blue flags look like?
