Thank you for your reply. Our life is very normal and boring. husband and I met dated, married, had 3 kids. We have a health marriage. Minimal disagreements. Nothing crazy or traumatic. Our other two kids are normal kids.
However, both husband and I have family history of mental illness and personality disorder. My mother is borderline, and I also think undiagnosed bipolar. My aunt is diagnosed bipolar. husband's sister and grandmother are narcissistic personality disorder. He and I can from families of origin with a lot of dysfunction, so that has been the big reason we have made or lives rather vanilla. No drama, no drinking, no partying (he and I grew up with partying type parents, unstable home environments).
My son, from my personal experiences, has very similar traits to Borderline and NPD, but both those can be similar in ways too. I hate to think that the awful people in my and DHs family passed their genes on him and now he has to suffer the rest of his life, and probably never form healthy relationships.
