Those of you with adult children, how did you teach your kids to be healthy, happy adults?

For the short version of the details section of this Q, just read the next paragraph, which I have highlighted in bold for your convenience. For those of you with longer attention spans, you can read the rest of the details.

Specifically, how did you teach your kids to avoid getting involved with unscrupulous, mean, lying, or narcissistic people?

How did you help guide your, now adult children, into successful relationships with mates/spouses/partners, who treat them with respect, kindness and love, and how to avoid getting caught up in abusive relationships?

How did you teach your kids how to figure out who the bad people were, without them having to actually get hurt or abused or humiliated by those people? Did they have to have the bad experience to learn the lesson?

Is it possible to teach young people to spot bad potential mates without them having to experience a bad relationship, directly?

Do you think it’s possible for young people who have had parents who were in a bad marriage/relationship/partnership, especially an abusive one, to be able to understand what a good relationship is, or does everyone have to have a bad experience to truly understand what a good experience is like, or can be like?

How can parents who have good relationships with their spouses/partners, teach their children that not all people will treat them with love and respect, and that they have to learn how to spot the bad people, and how to tell the difference between the good and the bad people before they get involved with them?

Is it just a crap shoot, or can parents actually teach their children how to avoid crappy people, especially the ones that masquerade as good people, especially when those masquerading are feeding their children lies that their children desperately want to hear and believe?

What do you do (or have you done) to cope with a child, a teenager or young adult (I know that legally there’s nothing to be done, but parents will still try to help their adult children) who despite getting advice from everyone from their friends, their parents, other relatives, maybe their teachers, and even strangers online, telling them that their mate is abusive, continues to pursue a relationship with the abuser, especially when the child won’t admit that the person is abusing them?
