text: if you like your best friend should you tell them? i have liked my best friend who is like my brother for a while now and he goes out with this girl that treats him so bad and i dont know if he will break up with her for me. he will eventually see how bad this girl treats him, so let him learn by his own mistakes.if you tell him anything negative about her, he may get upset at you!  just keep being his friend and once him and this terrible girl break up, you can express your feelings for him then if you feel the time is right.  otherwise, just be yourself and he'll realize how special you are, whether it's as his best friend or his girlfriend!   good luck!
