Don't give into the thought that your h will file for d. You know what the filing did to you. It is not a fun process. He won't enjoy it. It's a horrible decision to make and not one that is made lightly...no matter how much he screams it is what he wants. Once he starts on the path to trying to file...he'll regret it.
My h was horribly nasty to me V-Day. Said the most hurtful things! But you have to remember when we filed the d on them, we pretty much ripped their balls off and served them back on a platter! We hurt them so bad...they want to retaliate! You stand firm because you did the right thing trying to undo your mistake!
Encourage your h to 'do what he thinks is best for the family'. (hearing that statement made my h realize that it was not all about him!)
Keep the faith! God is greater than man! Don't go by what you see or hear...but by the Word of God. God says all things are possible through Him!
