Taylor Swift, I know you think you're looking out for your best friend Selena Gomez by reportedly encouraging her to break up with Justin Bieber, but you're making a big mistake! You're putting yourself in a no-win situation! Taylor, girlfriends shouldn't tell another woman to break up with a guy, even someone they're married to. I understand that you're worried about Justin's recent flirting with other women and how it may hurt Selena, but don't get in the middle. Listen, sympathize and support, but don't just blatantly tell them to break up because they'll only end up resenting you.
