Deep breaths. Take some time. WASs are the flakiest flakes on the planet. I am sure she meant everything said wrote in the email......at the moment that she wrote it. However, tomorrow, next week, 5 minutes later, etc, she may feel completely different! You cannot believe anything she says. And only half of what she does.
This is my advisement. Don't even acknowledge it. Just continue as if the email never existed. If she asks if you received it, just say "Yep." And then go back behaving as if the email never came.
Here is the thing, she sent if for a reason. SHe expects you to react. By NOT reacting she will be puzzled. She will wonder why. She may even get curious as to why it didn't get a reaction. But by not reacting you are not giving her what she wants.
And what she wants is for you to react someway. Believe it or not, if she is cheating, she wants to get caught. Then it is out in the open and she no longer has to hide it. Even though the romanticism of it (there is a thrill involved with sneaking around) will be reduced.
So just go about your business. Keep focusing on you. GAL. 180s. Detachment. There is no hurry on this. Every day that goes by makes it more likely that you will save your MR. Think of limbo as the gift of time! Many LBSs have been served D papers out of the blue, and come home to an empty house. As bad as it is it can always be worse.
