The idea of being bound by others' expectations horrifies you. In terms of love, you don't want to do what anyone else expects of you; you want to follow your own path, which is just fine as long as you're not doing it solely for the sake of rebellion. But lots of times, that's exactly the trap you'll fall into.
You might break up with someone special just because you find out that your parents or your best friends really like them, and see a future for you two. How contrary of you! But you have a hard time dealing with the pressures of what other people think you're going to do, or want you to do; you put a lot of pressure on yourself to keep everyone guessing. As you can imagine, that can wreak havoc on your love affairs. You might toss a perfectly good, intimate relationship out the window because it starts too look too traditional -- meaning, it starts moving toward a commitment, maybe even marriage or cohabitation. But really, what's wrong with those traditional values? You can reject limitations and restrictions without having to reject something that could bring you a lot of happiness and fulfillment -- namely, intimacy with someone that's really special to you.
