Have you considered acting a little more distant when you see your w? Especially now that she's working on a legal S? I think she's sitting on the fence big-time, giving you hugs and kisses when she sees you, just enough to keep you thinking she may be back, but still living her "happy" little life on the lake with OM. Maybe she's thinking that this is how it's going to be if you D? How do you think it's going to be?
I had an evil thought- I can't imagine it being very bucolic on the lake in upstate NY in the winter. I think she may decide she doesn't like that lifestyle much with the change of seasons. We'll just have to wait and see...
