Jim....TBH I thought about doing the same thing with my EW. One last stand, one last plea, one last are you sure, yada, yada, yada but in then in opted not to.
I just kept reminding myself to hold the line, she started this and she can end it. I reminded myself that I won't chase her, I won't pursue her and if this is what she wants then I will give it to her.
For me, letting her go, was my ultimate gift of love.
