I recall a saying I read and later told my wife "I know exactly what I bring to the table, that's why I'm not afraid of eating alone"
One of the things with my wife was her assumption we would be friends after, I was extremely clear I wanted no part of that fantasy and when she got emotional and asked why (after all the times we had) I explained to her even if I could get over the fact I was demoted from husband to friend, I would never ... Nor have I ... Kept a "friend" who had lied, cheated and stole from me, as my wife I would be open to work out the issues but as a friend as far as I was concerned it would be best to part ways and move on
