In response to your question, "Why does the WAS throw it all away?".
Well...whatever "it" was, seemed significantly stifling, boring, suffocating and loveless to them. They were bored and unhappy with their lives.
The classic mid-life crisis means that the world and its laws they once lived in no longer holds true for them. They are casting off their old personal and re-inventing a new one -- unfortunately, in many cases, they do it in a selfish, destructive and immoral way.
And I undersand your honesty about the difficulty in GAL. It's very hard.
There are two men on these DB boards who I have spoken with who did successfully turn their marriages around. But, they did it by not just practicing DB and GAL as techniques. They eliminated their fear of losing their wives and really went on a journey of self-transformation. It was not one of sensitivity and squishiness, rather it focused on being a brave, strong, true man of integrity who lives out the call to adventure.
Their wives noticed and were drawn to these new, strange, men.
I'll be honest with you. This is very tough.
