"In addition - we're married 5 years, 4 kids later and tons of money(it's all in business, and I don't see it anyway) my husband changed to the worst side. Money hungry type."

I can't say what your husband is like, since he isn't posting here. But you say he makes wads of money, and 1/2 isn't enough for you....I'd have to say you are more money hungry then him.
