You keep pushing but expect different results??? Let me tell you a week is NOT a very long time...my H and I were together everyday for over 27 years when he left...and we went months with NO contact....that was his wish...and we had kids! and a young son!!!
Your marriage is not over as of yet...and even with D it doesn't have to be the end but for most it is...and that is understandable...
You have the tools, you know what to do....if you really want to do this you will quit the panic and start thinking and planning on how YOU will deal with YOU...
My current advice would be to not take the call when she calls back...one of you has to stop "playing the game"...
