I personally think it is a complete sham. We know a number of people that have gone and the only thing that definitely worked was draining of their bank accounts. In the end, the ones that stuck together are still fighting about the same things and the others decided it wasn't worth it and split. It just took paying someone $1000s of dollars to make them recognize this.
I told my wife that if she ever suggested it, I'd just take the money and get an apartment.
Oh, and about getting blamed for things that are made up and compounded in her head- welcome to mine and every married man's life that I have ever met. It is the primary reason guys joke about women being crazy.
