Defining... Stuff

In a perfect monogamous utopia, a relationship consists of a two peoples' physical and emotional interactions. But, unfortunately, its 2011 and people get bored of one another so that means people CHEAT. Cheating. Most people would define that as, "when two people are in a committed relationship and one of those people is sexually  unfaithful to their partner." Sounds pretty solid right? I believe, most of the time, this definition stands true. But what happens when the situations isn't that clean cut? Does cheating only mean a physical encounter with someone outside your relationship? What about cheating on an emotional level? Intending to cheat? Is it merely the act of that receives this label? Imagine a man in a committed relationship with a woman. The woman is infatuated with the man, but the man's love and care belongs to another woman. Is that cheating? Picture two men in a relationship of the same nature and one of them uses a dating sight to talk to others. Sometimes people can even "cheat" for the right reasons. Is it still considered cheating even though it's not nearly so evil? Times are changing. The pious purity of relationships is seldom seen in today's dating or marital world. The introduction of technology has created other forms of encounters for people to access. Things can get complicated.
