i want to help my girlfriend, very important
I am 19. My girlfriend (19) has an ex boyfriend(19), so basically that was in childhood and the parents and school found out and it ended ugly, so what this guy does is he develops a grudge on her all these years, now he messaged her casually, and this dumb girl replied to him, he talked casually for a while but then he started crossing the line, he saved her private pictures from long back when they were dating and started blackmailing her, he started asking for her photos and forced her to do some nasty things, my girlfriend never said all this to me, when I questioned her one day, she said that he's teasing her and never told me this happened, she said she's tryna act friendly with him so he doesn't go rogue and do awful things, although I was concerned, she begged me not to do anything regarding it, she is shit scared of him, now her parents are kinda strict about boys and if they found she talked to him back or she has a boyfriend ( me ) , they would not trust her again. Now when I'm putting my girlfriend to sleep on the call, she said to me in half sleep, that guy raped her, she told me all the nasty things he had her do, like take pictures of her private parts and send him, make her do obscene gestures and getting naked over video call while he screenshotted them, she said he and another guy made her have sex against her wishes,this poor girl has been taking all of this by herself while fighting with me while I was oblivious to all of this, now if I ask her this when she's fully awake, she would deny this cuz she's shit scared of him and she has no proofs about the above events, even if I do something she would deny everything,
I can't go to their parents cuz they are kinda influential and they wouldn't trust her again, she also spoke about killing herself frequently and how she doesn't have the courage to do that, I am genuinely concerned for her right now and I want to help her, now what should I do?
