“You have bewitched me body and soul, and I love, I love, I love you. And wish from this day forth never to be parted from you.” - Pride and Prejudice 

I loved her against reason, against promise, against peace, against hope, against happiness, against all discouragement that could be.

― Charles Dickens

"I have for the first time found what I can truly love-I have found you. You are my sympathy-my better self-my goof angel- I am bound to you with a strong attachment. I think you good, gifted, lovely: a fervent, a solemn passion is conceived in my heart; it leans to you, draws you to my centre and spring of life, wrap my existence about you- and, kindling in pure, powerful flame, fuses you and me in one." - Charolette Bronte, Jane Eyre

I  have been astonished that men could die martyrs for their religion — I have shuddered at it. I shudder no more. I could be martyred for my religion. Love is my religion and I could die for that. I could die for you. – John Keats
