Demon inside of me looking in the Mirrors

Finding a great guy to date nowadays seems impossible for some women, so when she finds what seems like the perfect guy, she should go for it, right? He's cute, he's funny, smart and you two really seem to hit it off. You like him and he likes you, so what's stopping you two from hooking up? The dilemma: He's your best friend's brother. What to do?! A girlfriend of mine found herself in this predicament. I didn't quite see anything wrong with it...at first. I mean, what's the big deal about dating your best friend's brother? She had known him for years and he was a great friend of the family. They flirted here and there, but her brother just chalked it up to his younger sister having a little girl crush on one of his friends - until she came of age. At first, she started seeing her brother's friend behind his back, but once it got serious, she confessed that they had secretly been dating. Her brother wasn't too thrilled about it.
