Daughters of narcissistic fathers (as well as mothers) tend to become people-pleasers with porous boundaries in adulthood. As a result of the neglect and abuse, daughters of narcissistic parents can suffer from boundaries that are too porous.
The absolute truth. They will do anything, even sacrifice their children, to get their way! I know this to be true, I have a DIL that is a classic narcissist and I've seen the damage she's done already.
