MyPottersClay, I think it's great that you have changed your life and that you love the Lord and your'e letting him mold you. But I think that you need to keep praying for your wife. I usually hear this type of story with the table's turned, it's usually the women who wait for the the husband. I think you need to tell her to go to a rehabilitation if her problem is drugs and definitely don't give her any money. I'm not sure what the situation is exactly. Does she work? Best thing for you to do is to show her the love of Christ and encourage her to change. I know it's hard because it sounds like you don't love her anymore. I believe you said that you had the addiction before. I'm sure it was very difficult for you to give up drugs if you did do drugs at one point. So having come from that place you have to understand her also and know she may not be as strong as you. Just keep praying for her. The marriage is valid in the eyes of God. You are not committing adultery with her. She is your wife.
My advice to you is that you have to keep praying for her. I'm sure it's really hard to give your life to God when you have an addiction. But all things all things are possible with God. Just keep praying.
Hope this helps and God bless you brother
Father God, I come before you and I ask you for MyPottersClay, you know his situation and you know how difficult his situation is. I ask you to give him the wisdom and the patience to be there for his wife. I ask you for strength for both of them and I ask you to move in both of their lives in a special way. You are a God of miracles. Keep ministering to her heart God that she learns to appreciate her husband and realize that she needs to make that change in her life now and give her the strength to do it. In the name of Jesus Christ I pray. Amen.
God Bless you brother, I will keep you in my prayers and your wife.
