First, welcome. I know this is probably the last place you want to be, but there are some very friendly, very helpful people here, and most of us do understand what you're feeling.
I know it's hard, but in order to help you, we are going to still need more specifics. For example, how long have you and your W been together, do you have children, is this your first marriage.
Also, has your W been LD from the begining, or have things 'cooled off' at some point? How are the 'other' areas of your marriage? Do you two get along well outside of the bedroom?
You'll learn a lot as well by reading some of the other posters here; this is a smart, brave bunch of people, and a lot of them have made significant progress in what might have seemed like a desperate situation.
