First of all, it sounds like you are an entrepreneur at heart. Never give that up! It is a drive some of us have - and even if you try to suppress it, it will keep rearing it's creative head! You can't hold down that beast for long... trust me.
I am sorry your husband doesn't support your way of thinking. That makes it very difficult to be yourself. Have you tried sitting down and telling him how it makes you fee to create a business? Sure, you may not have succeeded financially yet; but all of the great successful people in history have been great failures before they became known for the success that now surrounds them.
You now are trying to get a "real" job (ick - I hate that term!) This will allow you to bring money into the marriage that previously wasn't there. Maybe he feels the pressure of providing for the family, and that is why he is so angry. But I promise you, as a creative entrepreneur, even after you start a new job, you are going to get an idea one day soon that you are going to want to pursue. You have to follow that idea, or you wouldn't be staying true to yourself.
Some people just don't *get* entrepreneurial thinking. They see it as being "lazy" and a "waste". They may not get it for now, but when you start making money from it - THEN they will be happy.
I suggest just explaining why you enjoy doing the things you do to your husband. Tell him that you are willing to try a traditional job; but you simply will have to go after your next idea. This will make you both happy!
Something to think about... can you teach your idea on the weekend at community classes? How about being a coach in the field of your liking? Perhaps, if you create tangibles, you can sell them on craigslist and ebay? The holidays are coming - you can rent booth space and sell your item/service... The ideas are limitless! Email me back if you want any suggestions - THIS is what I love to do! :)
