OK, ladies, here is the self-help guide we have all been waiting for.

Throw away all your magazines with their "Ten Signs He is Ready to Date You" and "How to Know When a Guy is Into You" articles.

Greg Behrendt and Liz Tuccillo have brought you the cold, hard truth with their new bestseller, He's Just Not That Into You: The No-Excuses Truth to Understanding Guys.

Who better to give advice than a writer and a consultant to Sex and the City?

Behrendt's male point of view is the key here.

We all know what's right and wrong in relationships, but we all make excuses for the wrongs when we really like someone.

Let's face it, girls, sometimes we just need our own common sense reinforced with a male perspective.

Behrendt and Tuccillo's book is built around a series of hypothetical situations in the form of letters written by women and addressed to Behrendt.

Tuccillo gives the female perspective on how women interpret men's actions and Behrendt gives the male perspective.

Not surprisingly, the answer to every woman's query is never complex and usually obvious.

Because, let's face it ... men just aren't that complicated.

They also do not think about relationships about half as much the time as we women do.

So as Behrendt and Tuccillo's book explains, when you meet a guy on Thursday and he says he will call you, but then doesn't call until Monday, it's because he's not that into you.

He had something better planned for his weekend that didn't involve you, so he saves you for during the week when he has nothing else better going on.

You're on the back burner, get over it and move on.

And if you're thinking that maybe he was busy or something came up, just look at how Behrendt puts it.

"With the advent of cell phones and speed dialing, it is impossible not to call you. Sometimes I call people from my pants pocket when I don't even mean to."

And here is the chapter with a message every college girl should pay close attention to.

"He's Just Not That Into You if He Only Wants to See You When He's Drunk."

This one is tough, especially at college, but we all know that even in this atmosphere, if he really likes you he'll have the nerve to call you sober.

Nope, it's not rocket science that this book preaches.

However, the book does a brilliant job of making women own up to what they know about men that is already true.

For those who still make excuses, this special little book even has a, "What You Should Have Learned in This Chapter" section at the end of each chapter.

And what you should have learned from reading this review is, if you haven't read this book yet, chances are you still don't know that he's just not that into you.
