I am sorry you feel stuck. That is not a good place to be. Most times I felt stuck, when I looked at it closely, I figured out I had put barriers in my own path. I thought it was the situation but actually there were choices I didn't make.
What specifically are you stuck with? As for the house, if you feel you want/need to sell it, take steps towards that. One of those will involve H but there are surely other steps you can take alone . Why is discussing this with H such a big deal? If your life, a better life is at the other side of the house sale, then this will need to be done sooner or later.
Best wishes
