I notice you are very indirect. So, I am going to ask a blunt question and I want a very blunt answer.
Do you want a divorce? Yes or no. Very simple question.
I don’t want to hear about all your wife’s issues. I don’t want to hear how your response is contingent upon "changes" you wife makes. Or how "you wanted to be married but don't know anymore."
I don’t want to hear anything more about all the failings of your wife and how much you have suffered because of her.
Yes or no: Do you want to stay married to your wife—as she is right now. Without any changes on her part.
