It is not my husband's actions that keep me standing but God's promises. I know that it is sometimes hard to hear God's voice or know his instructions but if you were going down the wrong path He would get your attention (and He did when your marriage fell apart). Now you probably are praying for your marriage and husband more than you ever did before. Right?
Are you really stuck in unforgiveness or are you just struggling with it? It is hard to feel like you are letting go when you continually pray for someone every day and through out the day. Forgiveness is not easy. When you are praying for someone you just don't walk away from the situation. Stop trying on your own and ask God to help you. Keep asking God to help you until you know that you have forgiven everyone = including yourself.
