So my friend just came over to my house bawling her eyes out and she wouldnt tell me what happened but said it had to do with her boyfriend. that was like an hour ago and now she finally told me and shes still crying really hard but she said her boyfriend and his friend raped her and i saw on her arms she has some bruises and on her side she does too! im really scared for her because he said if she told anyone he would hurt her and do it again. she was a virgin until now and i dont know what to do i cant get her to calm down but she said she still loves him and wont call the police and i dont want to call the cops because im her best friend and respect her wishes but im so scared for her and feel so bad! what can i do??? please PLEASE help!!!!!!
