“Only love can last.”

“Love between strangers takes only a few seconds and can last a whole life.”

“The only way love can last a lifetime is if it's unconditional. The truth is this: love is not determined by the one being loved but rather by the one choosing to love.”

“As a house can be only be built satisfactorily and durably when there is a foundation, and a picture can be painted only when there is something prepared to paint it on, so carnal love is only legitimate, reasonable, and lasting when it is based on the respect and love of one human being for another.”

“The joys of love...last only a moment. The sorrows of love last all the life long.”

“For there is always a sanctuary more, a door that can never be forced, a last inviolable stronghold that can never be taken, whatever the attack; your vote can be taken, you name, you innards, or even your life, but that last stonghold can only be surrendered. And to surrender it for any reason other than love is to surrender love.”
