W phoned and said we need to talk, and she wants to talk now rather than the weekend. So tonight FIL will pick up D7 and W and I will have space to talk.
I'm not sure why she wants to talk now. But my last comment before setting off for work was I was going to be home late so she could take as much computer time with her new friend as she wanted.
Tonight my opening gambit will be unless W sees a future lets just talk details of a separation there will be no need to talk any sordid details, I just want to outline a separation plan. Unfortunately we'll have to remain in the same house for a while as my option for accomodation at my brothers house has gone. Another one of my points will be to ask W to move out, I've done nothing wrong so why should I move out.
Anyway I've still got time to gather my thoughts I will post again later.
