I'm not sure about walking away. Do you think it'd be easier for you to do that? Is it what you want? i think that's the place to start from before you decide what to do. For me personally, I had to see if there was anything I could do to save my M; my H were really happy before the crisis stuff hit.
In relation to the money- do you think there's a way that you and H could discuss it without him viewin it badly? Or is there a way you can sort things out without having to speak to him directly? Maybe send him an e-mail outlining the problem and asking what he would see as the solution (or offering one yourself)? You need to protect yourself financially, IMHO.
Hope you had a good day today. I haven't seen your goals. Have you got some written?
