Mine has to be:
"The clouds I can handle but I can't fight an eclipse"
"Guard my heart, I left it with you"
and of course "And so the Lion feel in love with the lamb"

i really love the 'about three things i was absolutely positive'
and i also love 'forbidden to remember terrified to forget'

i have a couple faves actually...(the second quote is from memory, i dont have eclipse in front of me at the moment..so plz forgive any errorr:$)

1. 'And so the lion fell in love with the lamb'

2. 'Isabella Swan, i promise to love you forever, every single day of forever...will you marry me?'

This quote made me cry, i could feel the pain:( -
3. 'times passes. even when it seems impossible. even when each tick of the second hand aches like the pulse of blodd behind a bruise. it passes unevenly, in strange lurches adn dragging lulls, but pass it does. even for me'

and last but not least at the end of breaking dawn...

4. 'and then we continued blissfully into this small but perfect piece of our forever.'

i love when edward said: "It would be better for you to stay away from me. But im tired of staying away from you, bella."

"You held out your hand and I took it without stopping to make sense of what I was doing. For the first time in almost a century I FELT HOPE" <3

i love all of the qoutes just mentioned ,plus more...i also love the qoutes where he's telling bella "Before u my world was completely dark...well it was something to that effect...
