No, I don't think you can, really. My boyfriend and I, for example, are the complete opposites of what we thought we actually wanted in a person we could fall in love with. I always envisioned myself with someone who was smooth, articulate, the epitome of what a standard prince would be like, outgoing, and charming, with a clean cut appearance. While my boyfriend is outgoing and is generally sweet and smart, he's sometimes really bad with words and has a hard time being gentle or thinking before he speaks, and he has a more rugged appearance and has lots of tattoos, which I normally would be a bit turned off by. He originally wanted someone who was goth, a bit on the edgy and talkative side, and had big breasts, and yet he landed up with me, who's a bit more on the preppy side (though not quite...) and wears light, feminine colors with floral prints and ribbons and lace, quiet, polite, and generally sweet and caring, and doesn't have big breasts. Somehow, we just fell in love with one another, and I don't believe that if we each did manage to find someone who fit the bill of what we thought we wanted before, that we would go off in pursuit of that person instead.
