Square perversity.

Your challenges in relationships:

"I’ve come to understand after more than 20 years of reading horoscopes that no one is attracted to perfection. We’re much more likely to be drawn to our most challenging life issues. The astrological maxim states, "As above, so below," but even more primary in relationships is its continuation, "as within, so without." This means that, whatever your hardest aspect or toughest planetary pattern, your significant other will bring it home to you.
One of the first principles of natal horoscope interpretation I learned is that "we always go toward our squares." The chart shows, through the planets involved in hard aspect, where we will focus our life’s energy.
It’s much the same in relationships. Find the worst aspect in your own chart. Fall in love with someone. Then check that person’s chart. You’ll see that your beloved’s worst aspect is the perfect match for your own. Or try this: List the TV and movie actors you find yourself compelled to watch, the ones who you "just know" are your soul mates. Find their birth data – even just the day and year. Do they mirror your pattern?"

Oh god. Suddenly I know why I did this silly thing. Screeching damn karma and setting off all of my problems. No wonder I'm freaking fascinated by Mr. Famous and think we're alike :P And I'm not even a believer in karma/past life crap normally. Again, it's a good thing it's impossible that we'd ever meet, short of an act of God.

"I’ve learned over the years that we’re drawn to others because of what we need to learn. I believe that "soul mates" are people who get together to share important information about what they’ve learned in life. If someone falls into your patterns, that does not make the person bad, or even wrong. Your significant other is not your enemy. These people are your teachers. Parents often have kids that mirror their patterns, and aware parents know they have something to offer their children from their own experience. Conjunctions, squares, and oppositions are not problems, per se. They are energy. The people we are involved with in close relationships can teach us how to use our energy differently."
