I know this is going to sound cliche but I'm going to say it anyway. Then let go and let God have a go at him. Focus on your relationship with God, be with people that love Him, go to church, etc. Lift up your h in prayer. Go at it full throttle and see what happens. I think God put you exactly where you are for a reason. Just as I did, you see your m to a non-Christian as reason for what is happening to you now....punishment for a bad decision. Yes, bad decisions have consequences and are not punishment dealt out by God. God is the perfect parent. He hopes you will turn to him in times of difficulty as any parent would. He knows you realize the mistake you made but God can't be contrary to his word...He'll uphold your m as long as it is in his will to do so. You pray for your m according to his will and leave the decision of whether you need to go or stay up to God. That's what he wants from you.
I was in this same situation 45 days ago....my h and I went to d court. I wanted a continuance, h did not. So I left the decision to God in that through the judge God's decision for me to stay in the m or go would be delivered. God gave me the 90 day continuance so here I am still plugging away because I believe that God wants me here. I believe the same is true for you. Turn to God and let Him tell you what to do.
That's a big relief to know the maker of the universe can help you make this difficult decision of staying or going.
