Been reading your sitch. I know what it's like in regards to how things are progressing, with the filing coming up and all. Just remember, the process can last for some time, even after the filing process. Your wife will have to continue to push this through if this is what she wants. The filing doesn't mean it's over, although it FEELS that way.
My wife filed back in June, we had our first court date in July. Nothing since then. I even asked her to go ahead and just push this through and get it over with. She then put it in my court to proceed with the next step. She does however, continue to threaten it when she's upset.
I think you are on a good path. My prayers for you, your marriage and your family. They are worth the fight, right? Your new relationship with the Lord as well as a new you. Somehow, I think this is the most important part of what's happening.
If this is what you want, don't give up. There's going to be some really hard and confusing days ahead. Never give up on your God, your spouse or your family. Your wife and children are watching and your actions will have a great effect on the future.
