Love, Luck and Friendship

Are individuals unable to reach full potential without the interdependence of their "other self"? Aristotle and Aristophanes both argue that an individual is unable to achieve greatness and completeness without the help of another individual, which they explain as the other half or an extension of ones own self. They state that each individual has another self in the world, whether it be a lover or a true friend, everyone has someone who makes them whole, if they are lucky enough to find this person. Which can at first be found odd and off putting, it is clear that every individual has their own self, but what they argue is that we are not perfect beings but we search for someone else in order to help us acquire a taste of what perfect is. If these arguments are correct then should humans be able to guarantee success in relationships and friendships? If everyone has someone who can complete them should humans not strive everyday in order to figure out where these individuals can be found? It is my contention that there is no way to guarantee success in relationships and friendships, even if there is someone for everyone, there is no way for humans to guarantee these connections will be made or will last.
In Nicomachean Ethics, Aristotle argues and explores to great extent the virtues of friendship and what it means to be a true and righteous friend. He even values friendship over justice and honor because it is the thing man cannot go without, "And if men are friends, there is no need of justice between them; whereas merely to be just is not enough—a feeling of friendship is also necessary. Indeed the highest form of justice seems to have an element of friendly feeling in it" (NE). Aristotle proclaims that there are three different types of friendships practiced in the human world: that of utility, that of pleasure, and that of virtue. He also states that one cannot be the friend to inanimate objects, because there are no reciprocal feelings of good fortune wished upon the reciprocator. There must be a mutual bond of good fortune for there to be a true friendship. Aristotle argues that humans often set up relationships for each owns personal gain but if one is so lucky as to be of virtue, they are able to obtain a virtuous friendship which can be one of the most magnificent achievements one can attain. Our present state is of a failed or deficient identity, which we long to improve, or complete, that is the reason we search for friends, they can complete our being.
Aristotle\'s first account on the utility of friendship is described as for the old, "easily dissolved" or shallow (NE). He says this type of friendship is easily broken and based on something the other person can provide. These relationships are only used when beneficial. He uses an example of trade, where he argues that friendships of utility usually are between people that are opposite of one and other, in order to maximize the trade. This type of friendship is held between individuals who do not often care to have any deeper intimate relationship than what is already given, for say a person with braces and their dentist. They need each other because the dentist needs the money the patient is giving him in order to maintain his lively hood and the patient needs the knowledge, help, and skill set of the dentist in order to achieve a nice smile. They are friendly to each other, they see each other from time to time, and discuss the patients teeth, their eating habits, and the visit is over. Even though they might see each other frequently there is no real relationship the two share. This relationship can be considered for the old or the young because they "… are at such a time of life pursue not what is pleasant but what is beneficial"(NE). Neither type of individual are in the pursuit of pleasure, they are in demand of someone who will take to their needs. These relationships are easily broken, when the relationship no longer benefits the benefactor in the proper way. If the elderly individual has a caretaker that
