Alex, reading your posts makes me think my W is married to you too!
It also made me realize where most of my fear and guilt come from. Having been a child of divorce (W too as "funny" as that is), I NEVER wanted to put my children through this...and still don't. I, and I am sure MANY others here, compleely understand what you are feeling b/c it is EXACTLY what I feel.
Right now, I view the whole thing as if I am watching a train wreck about to happen, one I cannot stop.
