I've never done this before, so here I go. I'm in love with my best friend. I've known her my entire life. She's so special to me. Over the past year she has been dating someone who is a threat to her. He is abusive to her but she feels she deserves it, so she deals with it. Beyond just that he has a history of blackmail. Only I, him, and the girl involved know about that but I cant tell my best friend because the girl who was previously blackmailed begged me never to tell anyone that happened to her. I've been in a spot of not knowing how to help her. She and her safety are so important to me but I just cant bare open that situation again for that other girl, she's moving away from that and I don't want to keep reminding her of that. I've been withdrawing from all of my friends since this started. Deleted my TikTok, Instagram, snapchat, pretty much any app that could distract me from helping her, but I just don't know what I can do. I could never bare being the reason she gets hurt.
