I'm sorry to hear this Rough. You need to take as much time as you need before responding.
My response that I wrote to my W when she asked me is somewhere around here. It's in my threads around December 23rd, 24th, or so of 2010.
The jist of it is... "Go do what you need to do to find your missing happiness, but I will not help you destroy our marriage and our family".
Hang in there.
