There's always the free will problem, though-- God is not going to make your H do the right thing. I won't advise you one way or the other, but just want to point out that even Charlene Steinkamp filed for divorce. Filing for divorce does not make the LBS a bad person (can't say the same for the WAS, though).
My best friend's sister graduated from an ivy league school (undergraduate)around the time she became a fundamentalist Christian. She really wanted to go to grad school, but decided if that was God's plan for her, He would take care it. So rather than sending out applications, she waited for schools to contact her; consequently she didn't get into grad school.
There is such a thing as being TOO passive. You have control over your own actions. Isn't DBing about taking control of your own life?
Not trying to you p*ss off, just putting that out there as something to think about. I really hope things work out the way you want them to.
