YourTango presents relationship expert Rachel Greenwald, who breaks down why he didn't call you back. She takes us through the process of learning why men do not call women back after first dates. Find out if you are the type of woman who is at risk of not getting a call back, and it begins with "the blahs", a woman who gives the one word answer to standard questions. Next, see if you suffer from iPod repeatability, the Oprah eyes, or how men call it the Park Avenue princess. If you follow this guide and avoid the Sadie Hawkins theory and let men dive into their inner caveman, you could drastically improve your chances of getting a call asking for a second date.
