You can do this...but if he wants to talk, then listen to what he has to say. You don't have to be the same room w/him or do things w/him unless you want to and can keep your expectations very, very low.
Be sure to thank him for picking up your S.
Good luck! You will be just fine if you can remember to stay detached. If he does something to bait you, excuse yourself and find something to keep you busy or change the subject. Don't get into a heated conversation over talks about the relationship.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
