Answer a question with a question and start a conversation.
It'll save you a lot of time trying to come up with the perfect response because she will probably clarify that she's not seeking a discussion about anything other than trying to nail down and then mock and criticize your [misinterpreted] idea of staying married somehow, living together and perhaps, dating others?????
Then again, maybe she comes back saying she is actually having some second thoughts about all this and trying to actually take your temperature. In that case, you want HER talking and expressing her thoughts and feelings to you (her pursuing you) versus you giving her a letter/email over sharing, being mean and/or pyscho-babbling.
Maybe "I think I've been pretty clear about my position. I don't want a divorce. Divorce is injurious to our S9 so I remain willing to try to work things out and rebuild an terrific marriage. End your affair and come home. What did you think I meant?'
The internet is 90% complaining and entitlement and I hate it because I deserve better!
