“When we are not in a romantic relationship, we worry about why we aren’t in a relationship and whether we ever will be. When we start a relationship, we worry about whether the other person will like us and where it is going. When we are in the middle of a relationship, we worry that it will end. If it ends, we spend hours wondering why and trying to change ourselves to become someone new. If the relationship doesn’t end, we worry about when it will take the next step, and the step after that.” – Amy Przeworski, Ph.D.
