No-one deserves to be put into such a miserable situation by such a selfish man. You may not be able to get over your husband's behavior, even if he is contrite and genuinely asking for forgiveness. This is why affairs are so dangerous. Trust is such an important part of a relationship, and once trust is abused it is almost impossible to trust again. If you honestly believe that your husband will be faithful from now on, both of you need to work on rebuilding your relationship from the ground up. You need to rekindle the feelings you had when you decided to marry and work positively to reinforce your relationship. If possible, getting professional advice from a marriage therapist will help. I hope that you can heal and that he has finally realized your worth.
