You could be very attracted to your lover for the sense of mystery that permeates your bond -- as if there's something wonderful you're just about to discover about them, and it's constantly just out of your grasp! You may be right; they're a mystery to you, and there could be parts of their personality or body of experience that would really enhance your life if you could just put your finger on it. But doing that is much more easily said than done.
In some way, this person wears a variety of different faces when you're together, making your bond a confusing one, even if it's tantalizingly so. You might even feel as if they've bewitched you in some way -- you feel addicted to the relationship as if it's a drug, and you don't know why it holds such sway over you! As long as you're both feeling this way, it should be an overall positive connection between you; but if there's an imbalance in feeling, that's when trouble could start. Your lover could let you down when the veils of mystery are parted to reveal just a normal person, not a mystical being at all. Clear communication helps. If your partner has some urge to create mystery surrounding themselves, deliberately misleading you -- even just for fun -- they shouldn't do it! Clarity is hard enough to come by between you without adding deliberate deception to the mix.
