It is not that she wants to destroy "someone else life" you are seen as property a thing rather than a human with feeling and emotions
Narcissistic parents from the off set think of their children as possessions that they can pick up put down and toy with for their pleasure.
I hadnt actually ever looked at it like that.... that all she wanted was to shake off the family and life i had built, and start me somewhere else... but it makes alot of sense...
