“A wonderful relationship consists of two people who manage to become children again. Living and loving each other as teenagers in one way: purely.”

“Two people who represent true love are those who manage to live in a world of their own.”

“Love is the free exercise of choice. Two people love each other only when they are quite capable of living without each other but choose to live with each other.”

“The mark of an unhealthy relationship is two people who try to solve each other’s problems in order to feel good about themselves. Rather, a healthy relationship is when two people solve their own problems in order to feel good about each other.”

“Love consists of this: two solitudes that meet, protect and greet each other.”

“This is fusion, when two people become one. They are so close and so well suited to each other that they blend together. They merge and can't live without each other after that.”

“I mean that to be in a relationship with God is to be loved purely and furiously. And a person who thinks himself unlovable cannot be in a relationship with God because he can't accept who God is; a Being that is love. We learn that we are lovable or unlovable from other people," Paul says. "That is why God tells us so many times to love each other.”

“An excellent relationship is pure madness to live in two.”

“Defining relationships over here? I see that even as the world plunges into darkness and peril, you two stand around discussing your love lives. Teenagers.”

“In any relationship in which two people become one, the end result is two half people.”
