“Maybe-- maybe love makes you suspicious and doubting. Is it true that when you love a woman you are never sure-- never sure of her because you aren't sure of yourself? ”

“When people say they love you, you just have to decide to believe them, because you'll never know for sure.”

“Relationships are mysterious. We doubt the positive qualities in others, seldom the negative. You will say to your partner: do you really love me? Are you sure you love me? You will ask this a dozen times and drive the person nuts. But you never ask: are you really mad at me? Are you sure you’re angry? When someone is angry, you don’t doubt it for a moment. Yet the reverse should be true. We should doubt the negative in life, and have faith in the positive.”

“You should never, never doubt something that no one is sure of.”

“When you protect yourself from pain, be sure you do not protect yourself from love.”

“Oh, you should never, never doubt what nobody is sure about.”
