I say ignore his e-mail. Indifference is the best thing for you as you plan & prepare. Take care of you. Fill your love bucket. Get him out of your head.
Best advice I ever got on this board was when I was told repeatedly that I cared too much & put way too much effort into it.
Just tonight I had a good friend tell me "you got so used to being neglected that any scrap of attention was a feast". His e-mail is a scrap. Ignore it. Find a real feast. After all you are the Dudess !!!
Love ya girlie
