I Fucked Up So Bad Update

My best friend may never forgive me.... This story is so messy... I have a male best friend if 13 years. We have always been NOTHING but friends. A couple years ago I made a female best friend. He didn't like her. At first I thought it was jealousy... But... She was so toxic. She was a pathological liar... She lied so much and got me in bad situations. She put me in a situation where I had a gun to my head. However... It was nice to have a friend that everyone didn't think you would date so I kept her around. She treated my best friend so bad. Spread rumors that he was gay. I never did anything to stop it. Now this next part... Is touchy. One day she told me my best friend had done something to her without her consent.... Now. She has lied about this stuff before. She has admitted to lying about this... But... I believed her... Because you believe victims... This isn't where I fucked up... He tried to talk to me because it spread fast... I ignored him... Then one day... My sister sent me screenshots from a conversation this girl had with one of her friends saying she lied because she no longer wanted me to be friends with him... I was disgusted... I trusted her... Here is were I fucked up... I pretended I didn't see it. When the police investigated I didn't say anything. I didn't stand up for him.... I finally reached out to him saying I knew the truth and told him how I found out. He got mad that I knew for so long and said nothing... Didn't bring the text to the police... And now his life is over... I ruined a 13 year friendship to save a toxic friendship. I don't know how I can fix this.... Believing her isn't what I exactly feel guilty about... It's finding out the truth... And doing nothing... Now I lost my best friend...

Update: I went to the police this morning.... I told the truth.... I'm most likely going to get in trouble soon because since I knew and didn't say anything I could be considered part of her lie... IDK yet. I told her I knew the truth and wanted nothing to do with her and she called me a snitch and other nasty things with nasty threats. As for my best friend.... We talked a bit after I came forward but he isn't sure if he wants to be friends with me anymore.... I deserve this...
