Maybe your husband is having guilt issues? Surely he must feel bad for the cheating. I know you said it happened in January but maybe before that too? I found out, easily, when they start hiding things somethings going on. You sound okay, with the affair, which I find a little odd. Is he crying out for attention? Maybe he really loves you but he doesn't feel like he is getting what he needs from you? Just a few questions for you. I know a relationship goes both ways, and communication between you needs to happen. Counseling maybe.
