I really hope your H is continuing to work through these "feelings" he says has nothing to do with you. They may not, but they obviously do affect you all the same. Stress from finances or other "environmental" external factors are notorious for wrecking havoc on a R. We men tend to get too wrapped up in our careers and our ability to be the family provider, to the point that the worry will drive us to an early grave if we let it. It's a huge burden -- especially in these very difficult economic times.
And unfortunately, that same stress can lead to a deterioration in the marital R as well, if we don't watch it. I know this effect very well, very personally.
I hope that your H will do what it takes to help himself in this, for all your sakes. I would suggest that if the matter is too great that he consider seeking some IC, both financial/career C as well as emotional/spiritual C. We all need help at certain points in our lives. And I was just as stubborn as your H likely is in rejecting the idea I might need such help, but I now realize how very wrong I was in that stance. Sometimes just talking to to someone who will listen impartially and patiently to us is all we need to recognize the course correction our lives might require.
At the same time, don't forget to take care of mommy. Okay?
