You are right that you would not be believed since you retracted your story before , and I ' m not going to pretend that your family would be in the wrong on that since , from their perspective , you ' ve made such claims before which turned out to be untrue . That said , however , none of this nonsense is your fault and you have an obligation to yourself to get and keep yourself safe . I would , if possible , take the advice of those who suggest recording his behavior . But even if that isn ' t possible , I ' d tell your partner all of this at the very least . Working off of the assumption that they don ' t have the history with the story and hence no reason to be biased in his favor . Life partners are for helping to navigate life . Let them help you , they ' ll appreciate the trust . Why do you feel you can ' t trust them with this ? If all else fails , refuse to show up . I know it won ' t be fun , I know you don ' t have an excuse they ' ll accept . If they all already think you ' re unstable , use that . Refuse to give an excuse . Say you ' re not coming and when they ask why , say something perfectly rational that will be taken as insane , like , I ' m exercising my rights an autonomous sentient entity . Then hang up and turn off your phone . You owe this man nothing , and while I can see their point of view , your family ' s peace of mind does not trump your safety . Please , please , please find a way not to go . My heart aches that you have lived this tragedy . The man belongs behind bars , but if you can ' t find a way to put him there , please at least stop being his victim . Sending you all my best wishes internet hugs .
