#1 - update your password. He doesn't need to be finding this site in your history or your emails to solicitors
#2 - "damage control": Maybe still send the email in your edited/solicitor approved layout when you see fit and feel confident in it. Do you need to talk to him about what you wrote (or does he feel the need to talk to you about it?). I vote just be upfront and honest.
"I was writing out options to gain clarity, and still editing to appropriately reflect my thoughts to you in a clear manner. Please consider the recent email sent to be my current opinions and thoughts on the situation"
And if he brings up anything in the "old" version that isn't in the "new" version just repeat the above. That you were still in the process of being sure you expressed yourself clearly, but he had read a draft that you revisited for accuracy.
Did he say something about it? How did you know he read it?
