Reward Theory of Attraction
What this theory basically says is that people tend to like (be attracted) to those whom they associate with rewarding events. In other words, people tend to be attracted to those that make them feel good or to those that remind them of people they enjoy being around. If a relationship offers more reward and pleasure than cost and pain than that relationship is more likely to continue.
