Looking to keep hope alive

[ALF213]

I really need some advice on how to handle this separation. We each have a place to stay (friend for W, brother for me) and we will alternate leaving so the kids living situation would stay as "normal" as possible. I originally thought our separation included working on our marriage, so I agreed. She later said she wasn't clear enough. That the separation is not to work on our marriage. She wants a divorce. So we are a week away from when she said she wants to separate. I really don't want to leave the house if she is sure she wants a divorce. If she needs space, then she can leave. I'm not sure what to do. Stick to the plan we had discussed, or let her know I don't want to separate and divorce, and if that is what she wants, than she can leave.

Any advice?
