"If someone has such a fierce energy as to send you 40 consecutive messages full of insults, to call up all your friends and colleagues and badmouth you; to blow up storms out of trivial matters; give you restraining orders as if you were a child or his slave; rough you up badly and then in the midst of it pin you down and have sex with you, and you can tell the sex is far from an intimate activity but an act of domination; if they summon your clan apparently to talk sense into you; if they embarrassingly drive you out of functions and quarrel you for hours; if they suddenly switch and start talking to you sweetly in the presence of other people, or acting lovey-dovey hours before both of you appear in a function together; if there's a quarrel every day about a different matter until you've lost the energy to argue and you just take all the blame...and you still continue to entertain vague hopes of reformation and reconciliation, your case is hopeless."
I follow the Author below, because he is a physiotherapist and one of very few who speaks so openly about narcissism and red flags which prove to be very useful as a learning tool.
I do not believe however that every case is hopeless, I believe there is hope for everyone no matter what you are going through.
Hope derives from thought, your thoughts become your actions. Actions change your life. Zen
