Even if you two aren't getting along, you feel intensely bound to each other -- which can be a good or a bad thing. This aspect's effects are serious in tone, and could feel restrictive, especially to you, like you're being held back in this relationship. You might find that your natural spontaneity and creativity are discouraged by your more somber partner, which you might not have anticipated.
Even if you feel thwarted in this relationship, you probably stick with it anyway, because there's such a feeling of karmic destiny between you -- as if you were fated to meet and fall in love. At other times, you could both wonder privately how you ever got in so far! You feel as if your lover is needlessly sober, even depressing -- not realizing that you, too, can have this effect. You have a hold over each other that isn't an enthusiastic or overly romantic one; instead it's based on some sense of responsibility, on the need to control each other, yourselves and your relationship. You could feel a sense of obligation to stay in the relationship, even if you aren't happy or if things just aren't working between you. In short, this aspect increases your chances of sticking together through thick and thin, which means that if your relationship has a lot of friendly, playful and romantic aspects to it, this can only enhance your bond.
