Slowly taking my balls back... If for no other reason but to have to give to the next woman😄
Sorry, but this made me chuckle... Personally I think you should get them back and keep them this time.
as for the rest of your questions, DB does work, because it's all about you. It's making yourself whole (balls and all), building confidence and love for yourself, making yourself someone only a fool would leave.
It doesn't sound to me your WW is to far gone, mine wouldn't give me the time of day but when I mentioned D she backed down, now two months later we are piecing, and that's after finding out about an A.
Did you read Cadets homework links? Start detaching, GAL and doing 180s, they are all for you, and if your true to yourself in doing them your WW may take notice, but even if she doesn't, you'll be well prepared to handle things as they come.
