Chad, sorry to see you here. It's not over yet, there is still hope. My W told me she wanted a D 2 months ago. I agreed and even filed separation paperwork to keep her happy while I worked this program. We're still not out of the woods, my hearing is next month, but W is telling me she loves me now and talking like maybe there is a future for us. Point is, there is always hope.
Couple pieces of advice: read DR, read a bunch of posts around here to see what other people are doing that's working, and give her space. Any time you feel like talking to her, come here and post something instead. If you do talk to her, do not say anything negative. Come here to let that out. This will take time and will require a lot of discipline and self-control. The faster you can get a handle on that, the better off you'll be. Good luck
