<human>: she is amazing, great we get along so well, we hangout a lot, text a lot and all that, I love her more than I love anything in this world (as a friend) and then am also in love with her, I realized this a while back when she told me she was in love with her coworker (M 28), for a second my body stopped feeling things and I still am in a shock, she is so into him, everything I though she feels toward me she feels toward him, now don't get me wrong her I want her to have everything she wants, If love for her is to be with someone else by all means I couldn't be happier for her, BUT! I can't stand and watch, I just can't I know it is immature and I should be more grown up than this but these feelings is keeping me a prisoner, I can't even focus on other girls I just keep throwing them out of my life even though they are amazing girls, so I need to stay away from her, without telling her how I feel that is not an option, how do I kill this friendship?

<bot>: In love with his best friend, she is in love with another dude, I need to stay away from her without telling her why
