Sign up for the newsletters at a minimum - you may be intrigued enough to buy the e-book. It is good stuff and I'll tell you - it works.
I bought the E_book and it was good.
However, if you sign up for the E-mail's (at makingherhappy) he now has a FREE download called 'break up busting 101' which is excellent. There is a link to it at the end of every one of his e-mails.
Go sign up and get the book. (COG, you too).
It has made a great difference in my relationship.
