I've been in your situation. I know the pain of heartache. It is a terrible place to be when your spouse doesn't want you. It is God's will that your marriage stay intact, however, you can't make someone behave the way you want him/her to. There comes a point when you have to let go and let God. It is up to your spouse to decide to follow God's way. If your spouse wants out of the marriage, you have to let him go. I know that is so hard to do. You can continue to pray and ask God to intervene.

Heavenly Father,
Thank you for hearing our prayers. Thank you that you are an awesome God and a miracle maker. Thank you for bringing people into our lives that lift us up. Lord, you are Lord of all! You are our counselor, our healer, our Almighty God! You are our source of strength, perfect love that casts out all fear. You are the truth, life, and you are our everything.
