Intimacy requires courage because risk is inescapable. We cannot know at the outset how the relationship will affect us. Like a chemical mixture, if one of us is changed, both of us will be. Will we grow in self-actualization, or will it destroy us? The one thing we can be certain of is that if we let ourselves fully into the relationship for good or evil, we will not come out unaffected.
