After spending some time together, you'll start to realize that your energies are mismatched. There just won't be much intersection in the basic ways that you meet life. Because you're so different in your approaches to almost anything, you'll find that when you're in contact, upsets and obstacles will come up with regularity.
This kind of thing will happen again and again until you can recognize that your ill-matched energies are actually creating obstacles. Issues will crop up -- you'll accidentally offend each other, for example, or challenge each other's sense of duty -- and you'll respond by getting irritated, blaming each other for things that neither of you can control. Unless you can face the fact that this frustrating energy is actually a product of your combined energies, it'll keep causing you trouble. Compromise will help a lot, as will resisting the urge to point the finger at each other.
