i 'm in a really awkward position . my best friend is cheating on his girlfriend , and my own girlfriend is telling me i need to speak up and reveal his secret . no idea what to do , and i 'm disappointed in my friend , too . that 's horrible . i 'd talk to your best friend and tell him how you feel firstly . you 're right . i 'm worried about having to possibly lose my best friend . i 'm worried about having to stick my nose in other people 's personal affairs . i 'm worried about my girlfriend being mad about me being involved in it . it 's all just a big hassle . if your best friend is truly a best friend of yours , they wo n't leave you over this . it is n't right to tell his girlfriend in my opinion , but it is good if you speak to him about the situation .
