How can I know if my husband has truly forgiven me when I hurt him?

Is he still bringing the situation up? Does he seem distant? If the answer is no sounds like he has forgiven you. My question to you would be -have you forgiven yourself? Do you bring up the situation up when other issues arise? The freedom of forgiveness has to come from within to experience it. I pray that you have repented and forgiven yourself so you can experience the love of your husband if he has forgiven you. If not ask God to soften his heart to forgive you, to love you and trust you again. Pray without ceasing. Believe!
