It certainly is important to know your H's stress triggers (money and providing for his family) and be sensitive to them. IMO that doesn't mean you need to fix them.
Reading your post above it seems he is more frustrated that he is putting his blood, sweat and tears in a business and not getting the financial return he thought he would get. And that alone is *very* frustrating when you work your ass off in a business. BUT anybody with an ounce of sense that starts a business needs to understand there is a very high probability that the business will not yield the profit they want/need and not having a fallback plan is reckless.
That alone could be the sense of failure and frustration he is feeling.
It is very good you are thinking of solutions to your financial crises. Solutions are a good thing and brainstorming ideas always is a great place to start!
The way I see it, one when person checks out of a marriage (in this case your H) no matter how many solutions you present to them for other life issues (in your case money) they are all band aids to the bigger problem.
Many, many people have lots on their plate... careers, schooling, children, extended family obligations, massive financial burden, having to work two jobs and so on. If those "outside" stresses really are the root cause of the marriage problems then both parties would be more than willing to fix/alter/repair the outside stuff to make the inside stuff better. While they may be contributing factors I don't think all that often they are the crux if the issue.
You said above your H struggles with the fact he cannot provide the same lifestyle as his dad did. Your H is a grown man. If he is still comparing something to his childhood the problem really is within him. Are you complaining about the lifestyle? If not then he is the one with the issue and he is the one that will have to own the issue.
I think many men (yes, I realize this is a generalization) measure their success as a man, husband and father by what they can provide. My H was very much like that. And while all those perks are nice (perks = extra stuff money can buy) most of the time what really makes them a success is too "touchy feely" for them as it requires self examination.
If you only have been separated for 11 days nothing has to be decided right now. IMO it's way to early in your situation to be thinking about such major moves.
Although it is a tough pill to swallow you can't fix anything with your H. If ALL your financial burden went away tomorrow can you say FOR SURE for the rest of his life your H will be 110% "all in" to work on your marriage forever? Right now you can only work on you.
