He's Just Not That Into You by Greg Behrendt and Liz Tucillo

This book really killed my self-esteem. The entire premise of this book is that if a guy is into you, nothing will stop him. There won't be excuses. Some people have told me that I am intimidating, so I let things go that most guys are shy. Apparently, that shouldn't stop someone either. If the guy is too shy to even talk to me, then apparently he's not worth it. Greg also says we should not do the asking, that guys like the 'chase'.

If what this guy says is correct, then does that not mean no one has been into me ever? I didn't think I was that bad looking or that awful of a person. In fact, I know quite a few wonderful ladies who also fall into this category. My question for Greg is what is wrong with the male population?! Can someone kindly explain? It makes me irritated.
