I was/still am in the same boat as you. If my W decides to D I know it'll frustrate me that she never even tried (together) to work on our relationship and keep our family together. It's heartbreaking.
My W recently told me that the person she was post BD wasn't her - she didn't recognize herself and she is sorry for how she acted. This "sorry" took 11 months. Even then I wasn't expecting it as we had Mediation with our L's booked for Nov 28th. She has since told me her feelings are changing and doesn't think it's wise to meet with the L's at this point...so we are holding off and giving some time to let the feelings sort out. In the meantime, I'm still planning on life without her as I don't know where this will end up.
My point is that these situations CAN turn around and her "truth" can change b/c it's based on emotions.
Let her face the reality of life will be like without you...drop the rope as best you can and only talk when warranted. Do NOT be the person to reach out. Get out and do things and let her wonder about you.
I hope you can work through it too.
