I'm in your same situation right now. I've fought for what I thought I could do to no avail. The hell we've both gone thought in the last 2 years was finally more than she could take. Unfortunately I have no great advice on how to save the marriage because I couldn't save my own. I just want to tell you that you're not the only one. We're not the first... won't be the last... and do what you need to do for you. Its taken a lot of loss for me to realize nobody's gonna make the effort for me. It sucks, but you need to do what you need to do for you. Peace be with you...
