Personally, I don't think ultimatums are a great way of moving forward but I do understand your frustration. It really does sound as if there is more going on here than the sale of the houses. For an undriven man, you have found yourself making many sacrifices in order for him to have the job he wants. That sounds like he is capable of doing what he needs to when he chooses to. One thing I would say though, is if he is a passive aggressive sort of fellow, the more you push, the more he'll resist. Have you tried telling him how unhappy you are? It's difficult for him to address without him being fully aware of how serious this is. A very serious, "We need to talk about our future," may have a better chance of getting attention than a packed bag which looks like you are throwing your toys out of the pram even though you might be fully justified!
37 years is a long time investment and if, on balance, you are happier than unhappier, then find a way through this. If it is the other way round, there are some serious decisions to be made. Maybe listing the pros and cons before having a very serious discussion of how to move on will help.
I do hope you get it sorted but maybe more work is needed on both sides to make your marriage more balanced or at least make it feel more balanced for you.
