Enlightened, Mary is right. Read DB. And she is also right about the process of healing from infidelity. You can't do it alone usually. You need your partner's support if your marriage is to heal. I understand that he doesn't like talking about it, who would? And he doesn't have to talk about it forever, but if the two of you don't deal with your issues sometime, somehow, how will you be able to eliminate the problems that lead you to this situation in the first place? Go get counseling. I hope he'll go with you. If not, ask him to read DB after you do.
