It seems like she wants to go through the divorce. You have been putting effort to save your marriage and she files you with a "not willing to accept a divorce paper". As a Christian, show her scriptures that God hates divorce. Also, you did not commit adultery so she shouldn't be leaving you as it says in scriptures. You guys made a vow that you guys would stick together through thick and thin and sickness and health, and it seems like your doing everything to save the marriage so you are in the right. You repented, prayed, and you are trying to change. God says to forgive, there's always ups and downs in a relationship and it's sad to see that she is giving up when you are truly sorry and is refusing to work things out with you. I advise to bring up scriptures to her about divorce..that you are not the one refusing the divorce..but God is the one who does not accept the divorce...you are defending the truth and what God says about divorce that's what you are doing. Do those things and as a true servant of God she would not go through with the divorce.
