Sounds like the whole Libra North Node thing.
Sun opposed ascendant/conjunct descendant:
"The Descendant intensely symbolizes what we don't identify with in ourselves, and therefore project onto or seek in others or through intimate relationships. With the Sun here you need partners or intimate one-to-one relationships to find your center, sense of purpose, and to fulfill your goals. If you're a man who judges himself, you may experience this part of your nature as disintegrative and demoralizing. But whichever sex you are you need others through which you - and so that you - can shine! This may be difficult to accept, but there is nothing wrong with this need or dependence. It just is. It is WHO YOU ARE!
Souls who have incarnated at sunset, as you have, often find or model their own will and sense of purpose on that of their partner. In your intimate one-to-one relationships your partner will be dominant and hold the power. This may occur through your helping them to shine or through your learning to adjust to their needs and their demands and by putting yourself second. You tend to find your sense of self as part of a couple rather than as a separate ego."
This kind of thing bothers the crap out of me. It nearly encourages you to be some kind of leech or something. You should be able to survive without a partner if you have to, for god's sake.
