You naturally take a practical view of life; you trust in the things that you can see, touch, feel and otherwise count on in a tangible way. You believe in hard work and responsibility, and anything more abstract than that seems untrustworthy or out-and-out silly to you. But there's a whole other side of things -- the intangible, the instinctive, even the psychic -- and your partner has a good grasp on these concepts.
They lead with their gut, acting on instinct and reaching out as often with their mind as they do with their hands. This can actually be threatening to you, if you need to stand on solid ground to feel comfortable. These differences between you could lead to episodes of intense controlling behavior in which you try to control your partner's sense of reality, in order to validate your own. But especially for you, the more practical (or cynical) partner, you've find that your attempts to control your lover don't work -- and they never lead anywhere good. Instead of setting up this pattern of attempted control and clashing of wills, why not do the hard work of learning to accept your differences? That's the only way that you two can get along. And it's certainly hard work, but as you do this, you can both learn a lot about how to blend the other's point of view with your own for a greater overall perspective.
