We are 4 years from being empty nesters, so I was trying to hang on. But wife has filed for divorce, about a week or so ago.
I'm following Iron Rule #7 of Tomassi and not trying to salvage just move on. She has initiated sex a couple of times since then, which is mostly the norm of our sex life. I know "I am the prize." But in that moment, I can't come up with a "no."

Just to put a fine point on it: Is it appropriate to continue sex? If not, help me with reasons to say no.
