If you see him for lunch at all, somehow put on a face that says you are looking forward to the next episode of your life, be it solo or with one of the many who are pursuing you. If no one is pursing you go out and be pursued. Then decide for yourself if you want to risk going through this again. Either way you have a whole lot to look forward to and you should show it.
Don't ever let him see you sweat.
I'll say a prayer for your strength and well being.
