Don't follow it up! Just leave her be! You don't have to tell her that, she'll figure it out in a couple of days. You have said lots of words up to this point, and have any of them worked? Just stop having the discussions - she'll also figure that out. It'll take some time.
I can just about guarantee, if she has feelings, she'll contact you.
I'm not bashing the intent of your email - I'm really not, but if you can take the focus of off the problem, and put that energy into solutions, you'll get somewhere.
The problem is that right now, your solution is time and trust - both of which are going to take a long time to build. Can you just do that? Leave things alone?
Start timing yourself - let's go for a day. When the alarm goes off tomorrow, let's go for day 2.
I remember doing this, and through day 12 for me, it was rough, and day 13 was a ripper. But day 28 was awesome, sunshine, happiness, and freedom. I loved my wife more on day 28 than I did on day 12!
