You focus together on ascending to greater spiritual heights, and you can both develop, through this relationship, a greater sense of awareness of the universe and yourselves -- as long as you take care to communicate well with each other. You inspire each other to adopt new ways of thinking. For example, you tend to be what you think of as a realist, but that realism is truly more like cynicism, pessimism or even an occasional lack of emotion.
This relationship helps you open up your soul a little bit and soften those hardened layers of doubt and mistrust toward the universe. If you've gotten used to controlling your environment and relying only on the things you can see, touch, feel and so on, this relationship can help to open you up to the intangible. Your lover has much more of a grasp on the intuitive and emotional side of life, and helps you to get in touch with your subtler feelings as well. In return, you retain just enough of that grounded practicality to help keep your lover's feet on the ground. The two of you might actually do some hard work in a spiritual arena, which comes in the form of long discussions that cover abstract subjects like psychic ability and so on. You might want to try taking a class in mysticism or some other spiritual pursuit together, or pursue some other formalized route toward enlightenment.
