It's still not hopeless, this is a very emotional time for all parties involved.
I strongly encourage you to stick around here, even if you've giving up on your marriage.
You can learn some very important things about relationships so that you won't repeat them in the future with W or with someone else.
You are acting on emotion right now. And one thing I know all too well, when you make decisions based on how you are feeling emotionally at the time, it will almost always blow up in your face.
Take some time to cool off and find your path, my friend. I hope you will stick around.
