When you fall in love and make a commitment for the long term, it will probably be with someone very different from you. They may even be from another country and a completely different cultural background, but they will at least have been brought up with different values and beliefs than yours, or in a different socioeconomic background. You're excited by people who present a brand-new way of living or looking at the world -- people who broaden your experience and philosophy just by being who they are.
An educated lover is certainly not a must, but that would be another possibility, because in some way, you want your sweetie to broaden your mental horizons. Also, your long-term love will be with someone who demands their own independence and encourages yours. You may not have a traditional relationship in terms of living together, eating dinner together every night, checking in with each other when one of you isn't around and so on; you'll work out a relationship structure that's right for the both of you, and it may be very unorthodox. Freedom, independence and philosophy will always be a part of your relationship, as will adventure and fun.
