Some faults must be tolerated, while others must not. Severely unstable people will ruin your life if you let them in. It will happen even if they don’t intend for it to happen. By definition, an unstable person is someone who can’t control themselves.

Cognitive dissonance, where actions and words are not aligned, is something you’ll always have to contend with. Even the most honest people can exhibit cognitive dissonance without realizing it. Even well-intentioned people may need to be kept at a distance if they cause too much inconsistency and unpredictability in your life.

Balance empathy with self-preservation.
