You might want to wait a little on the "talk". Just my opinion of course....maybe till after Greece gets eliminated from the world cup. I know your husband is a smart guy. He realizes he has nothing to gain and everything to lose in a conversation about his affair. I doubt he can say anything about it that can make you feel better...there is NOTHING "normal" about this type of discussion. Not with him...maybe between you and a councellor to help you overcome some feelings.....maybe in the future when things are more stable...maybe I do not know what I am talking about.... The feelings and thoughts you have on a recurring basis may be more than normal....but they are YOURS. You have to deal with them and try to minimize their effect on you and on your relationship today.
