I wish I had the answers. I am so scared for the day that I might have to face this. I do agree with Yankee, though, that you should definitely take more time to think about filing. Rushing it in the heat of the moment because you're feeling hurt may only feel good for a moment because you think you now have direction, but you may end up making a decision for him that he may still be on the fence about.
The way I see it, if you still believe in the two of you... then keep believing. There is nothing wrong with wanting to save your M. And as for the trust issues, those things will most definitely take time but can most definitely be resolved. There will be a lot of effort that will need to be given from your H but don't give up hope that you will never trust him again.
I've had to read DR several times recently to help me keep things in perspective, along with reviewing my thread as well. I know he is somewhat forcing you into a negative situation with the way the finances are going but you just never know... something may happen that will jolt everything he thinks he wants and he may suddenly start to shift his way of thinking about your R.
Keep up your DBing even though it is hard. If anything, you'll know that you tried everything you could.
