Why We Form Relationships

There are many reasons why people form relationships. I think that I have formed relationships with people based on appearance, similarities, differences, liked someone purely because they have shown interest in me. However, the relationships that have lasted the longest were based on the saying "opposites attract". I find that when I do have many similarities with people, its not that I do not get along with them, but I feel I also need a person who compliments me. I am always known as the shy, quiet person who does not usually say much to anyone. This is especially true in a social situation. The relationship that I am in right now definitely fits the "opposites attract" saying because he is the exact opposite of me in social situations. He will say just about anything and do just about anything even if it is slightly embarrassing. When we go out places he is always talking to people and being the "loud, attention drawer". This compliments/makes up for me being the less talkative type, but also makes me push my envelope in order to become friends with his friends. He definitely dominates the social aspects in our relationship, but I compliment him in that I have much stronger work ethics then he does.
