He wants somebody to feel sorry for him. Well, he made a choice to go outside of the marriage and do what he did/is doing. Now he is going to run away and then come back a little and run away some more.
What does he need you to do next week? Honestly, let him do all the work if it is something he is involved in and make yourself unavailable.
