From “The Emotional Incest Syndrome” by Patricia Love with Jo Robinson.. Exploring the dynamics of covert (emotional or non-sexual but gender-related) incest.
From page 17:
This is the sad truth about emotional incest. The only relationship that can come close to satisfying an adult is a loving, intimate relationship with another adult. A child lacks the wisdom, the experience and the skills to be an adequate partner.
And it goes without saying that a child must never be a parent's sexual partner. While a child may appear to be an adequate companion for an adult, there is always something missing, and tragically, the child bears the brunt of the parent's frustration.
