Proximity: Frequent contact predicts closeness.
Similarity: Shared attitudes, interests, values and experiences are rewarding.
Self-disclosure: Intimate sharing builds trust and allows us to know each other.
Physical attractiveness: We find beauty rewarding.
But the Expectancy-Value Theory says we weigh the value of the reward against our expectation of success in a relationship.
My theory, then, is that when we’re ready to manifest our true value, we’ll go for what we really want in a partner, knowing that we’ll be successful.
