How to spot a serial dater

 I have friends and acquaintances who are serial daters. One in particular is so hooked to this duplicitous dating game. It is highly unlikely that she has ever been single for more than 72 hours. She always has a man in tow because she has different men constantly coming and going out of her life. The drill is usually the same. She meets a guy she is absolutely smitten with. She seems genuinely thrilled about her new-found love interest. A few days later, she walks out on him. Nine times out of 10, the reason she gives for dumping the guy is shallow and superficial. The next day you, find her snuggled up with a new guy whom she claims she is also crazy about. And the cycle goes on and on.
