I totally understand and I am so sorry you have to go through this. It is hard to love someone that is not able to return that love. Notice I did not say "Does not love us back"? That is because he does love you. You cannot be with someone that long and not love them unless there is abuse. He hasnt stopped loving you, he just doesnt know how to show it anymore. He has let his sexual addiction take over and his heart has stopped functioning. It is not that unusual. Men that have sexual addictions shut down after a while because once the addiction takes over then the heart ceases to be in control. His mind is completely consumed with his addiction and he has given over to it. Letting him go is the right thing to do but that doesnt mean that it feels good. It is what it is and unfortunately the innocent suffer but when it all is said and done, he will be the one suffering. When the other woman takes off and he is alone he will turn to you and his sons and all will be gone. God can restore and heal, of this I have no doubt, and if that is what God's plan is then so be it but dont feel you need to wait. This is his choice. Let him live it because ultimatly he will pay the highest price. Dont let his current circumstances fool you. He is tormented inside. My husband lived everyday as if he were dying inside. I love him still but I cannot undo what has been done. Hang in there my friend. There are better days ahead.
