This relationship will be nothing if not emotionally intense. In fact, it will have a profound transformative effect on both of you. If you stay together for any length of time, it's almost impossible that you'll remain unchanged.
You'll teach each other everything you know about life and love, but more than that, simply being together and interacting will shift the whole way you think about the important things in life -- your general outlook or philosophy, perhaps, or the way you deal with your emotions. Your self-expression will also change a great deal through the course of knowing and loving each other. You'll deepen in your self-awareness, and you'll be able to use this knowledge to enhance not only this relationship but your connections with everyone in your life. The sexual connection you two share will also be highly emotional, and you'll both derive a great deal of emotional sustenance from your physical bond. This will be an important part of your connection.
