after 3 years of thinking i had no proof that my ex sa’d i finally found some, my ex has been going around saying im lying and making me seem insane for 3 years now. i’m friends with both his sisters (one believes me one doesn’t) so i’m always hearing what he’s saying about me. i always wanted to find proof and expose him to his friends and his gf instead of the police. but now idk how to do it, his sister wants to help me but i don’t want him knowing she’s involved so i gotta be careful, which is what’s making it hard to know what to do. does anyone have ideas?
