watch your expectations regarding gravity and remorse. because W's affair was interrupted (vs. dying on its own accord), it may take her longer to develop perspective.
also, pay close attention to the therapy process. if it becomes solely focused on her affair there is a risk she will disengage and/or drop out. allowing therapy to be a balanced forum may be very challenging for you to do because of your own emotions. yet, if the ultimate goal is to save your marriage, you'll need to do some difficult but rewarding things.
