Self-help for your mistress

As I was perusing the shelves at my local bookstore, I couldn't help but notice this title:

"Will He Really Leave Her for Me?"

I thought that I had misread the title. I mean, I had to have misread. A self-help book for the mistress???

I'm thinking that I could sum this book up in two words: highly unlikely! Is there really much more to say? Except maybe, DTMFA! I just don't feel that there is any hope in waiting around for a married man. And if he does leave his wife for the mistress, what kind of relationship would that be? Could there ever be any unconditional trust in that relationship? Personally, it would be a long time before I started to feel completely sure of his fidelity. If he did it to one woman, what makes me immune from him doing the same thing to me?

I guess this book has some insightful information for someone, however. It's current rating is 4 1/2 stars. Still, I can't help but feel that any information that is presented in this book is anything that a woman in this situation hasn't already heard before. But I suppose maybe she's heard before and wasn't ready to listen.

I still say just DTMFA and be done with it!!!

Any other thoughts?
