If you're looking for a relationship that allows you to nurture someone and be nurtured, one that provides a foundation of support that enables you both to become more fully and joyfully yourselves, you might want to keep looking, because this one probably isn't it. It's not that you don't want to do and be all those things for your lover; you do. But this relationship runs along tracks you don't anticipate, powered by a force that is bigger than either of you.
Instead of supporting and nurturing your partner, you try to dominate and control their behavior and feelings. Power plays and arguments could be frequent occurrences. You grow jealous and possessive of them, making it hard for them to just be themselves and have a good time, even when they're not in the same room as you. The bad feelings you create together in this relationship could last for a long time. You might have a troubled sexual connection that convinces one of you there's something wrong with you, or that you're not a good lover. Why put yourselves, and each other, through this kind of trauma? If there aren't an overwhelming number of other, easier, more harmonious aspects between you to ensure a positive connection, you might be better off looking for love someplace else.
