There comes a time, after we go through a Radical Acceptance Grief, forgive (or not), reconnect with our inner power, learn to keep our boundaries firm while being gentle, lead our life differently, never fall for any manipulation strategy again, show detached love (if it is possible for us, never forced), when a behavioral shift takes place because they are now looking up to you for inspiration and realize your boundaries are unbreakable and need to be respected. It doesn't mean they wouldn't try from time to time (the delusional grandiosity always gets them). It only means that your newly developed consistency and emotional maturity eventually pay off!
