People need to be overall healthy to care for anyone they love in life for your information.
Personally, anyone starting the issue first is the issue. They started it first. The rest are their repercussions. The most empathetic/kindest people have limits too. After few chances [warnings] first (maximum)? Never be surprised for a 360 degrees change in others’ behaviours when your always immoral first via cruelty first on purpose first, so stop blaming others after obvious chances given to you first. You had your chance(s) to be a virtuous person. Don’t call anyone hypocrites, narcissistic, evil, etc., after yous are clearly/directly warned (hidden chances/forgiveness) first.
Many people abuse the term the narcissistic. I 100% peacefully love myself. I’m never evil, disrespectful, inconsiderate, etc., to others first via cruel intents first on purpose first. I spoil myself because I’m always doing my best for peace, and I prefer to be independent too. I believe one must truly love oneself in order to truly love others as well. Loving oneself is a need; it’s self-care. Caring for others needs energies. If being good person in my personal methods to others are narcissistic, I’m a narcissistic to yous [When in fact, I’m simply peacefully loving/caring mine/others’ overall-health]. Also getting away from anyone for whatever reasons to sustain peace of mind is expected/normal.
Say, a person is manipulative, fibbing, inconsiderate, etc., first via selfishness first on purpose. Keep in mind that manipulative, fibbing, inconsideration, selfishness, etc., are describing words.
A simplest case: If a person is truly overall-mean, that is simply who he/she is. Sometimes describing a person is just that. Merely describing words. It is what it is for many people as well. They actually don’t have a legit mental condition nor personality disorder. Some people are merely who they are.
