Pray for our Marriage

My husband and I have been struggling with our marriage. He has left our house and is living with his "friend". I am so torn and reach out to God to save this. I pray for him more than I pray for myself. I ask God to remove all the demons that he is battling. I also ask God to help me forgive him, as I am struggling with this. Please pray for our union to not be broken, but to be stronger than it has ever been.
