"You listen to me. [Kneels in front of her] I’ve been alive a bit longer than you, and dead a lot longer than that. I’ve seen things you couldn’t imagine, and done things I prefer you didn’t. I don’t exactly have a reputation for being a thinker. I follow my blood, which doesn’t exactly rush in the direction of my brain. So I make a lot of mistakes, a lot of wrong bloody calls. A hundred plus years, and there’s only one thing I’ve ever been sure of: you. [Buffy looks away; he reaches toward her face] Hey, look at me. I’m not asking you for anything. When I say, “I love you,” it’s not because I want you or because I can’t have you. It has nothing to do with me. I love what you are, what you do, how you try. I’ve seen your kindness and your strength. I’ve seen the best and the worst of you. And I understand with perfect clarity exactly what you are. You’re a hell of a woman. You’re the one, Buffy."

Still takes my breath away. Hahaha.
