The problem is that if your wife doesn't get over this jealousy then there may appear some more "consequences". I know that it is easy to be jealous of the attention that you are giving to other women through pornography. But it is more important to find a different approach, cause it's your wife's problem, not yours. The question your wife needs to ask herself is - is this something that will break up relationships with this man or we'll get over it and find more pleasure being together?
