I will share with you all what I consider the most profound statements and gestures of love I have seen so far on film or television (in no particular order).

Why does a man do what he mustn’t? For her. To be hers. To be the kind of man who would ne… To be a kind of man. And she shall look on him with forgiveness… and everybody will forgive and love. He will be loved.

Uncomfortable silences. Why do we feel it’s necessary to yak about bullsh*t in order to be comfortable?
That’s when you know you’ve found somebody really special: you can just shut the f*ck up for a minute and comfortably share silence.

So, yes, I know that love is unconditional. But I also know it can be unpredictable, unexpected, uncontrollable, unbearable and strangely easy to mistake for loathing, and… What I’m trying to say, Tristan, is… I think I love you. My heart… It feels like my chest can barely contain it. Like it doesn’t belong to me any more. It belongs to you. And if you wanted it, I’d wish for nothing in exchange — no gifts, no goods, no demonstrations of devotion. Nothing but knowing you loved me, too. Just your heart, in exchange for mine.

My dream is of eternity with you… I offer you this rose… my heart… my soul… my love
