Hmmmm, the implication here is that if a parent WERE feeling threatened that a new partner was replacing them.....then it's because s/he secretly believes that they were not properly loving with the children, that the children would have some unfilled need that this other person could potentially fulfill. Again, this assumes the new partner made NO indication that was their goal (in that case, the fears would be justified by an entirely separate factor).
