I'm a Leo, and I'm married to a Leo. We do have issues related to what our signs typically represent- leadership, selfishness, materialistic leanings, etc. The main prob is that I'm not like most Leo's- my mom says my Pisces moon cancels out my Leonine tendancy to be materialistic and makes me value the spiritual side of life more. I can't say that she's right as to the reason but I don't seem to follow the norm with regards to Leo behavior, excepting the big hair, of course.
(If I were a true Leo, I might tolerate my spouse's behavior better, although I suspect we'd be in the poorhouse).
