Glee Quotes

We met right here. I took this man's hand and we ran down that hallway. Those of you who know me know I'm not in the habit of taking the hands of people I've never met before, but I think that my soul knew something that my body and my mind didn't know yet. It knew that our hands were meant to hold each other, fearlessly and forever. Which is why it's never really felt like I've been getting to know you. It's always felt like I was remembering you from something. As if in every lifetime that you and I have ever lived we've chosen to come back and find each other and fall in love all over again, over and over, for all eternity. And I just feel so lucky that I found you so soon in this lifetime because all I want to do, all I've ever wanted to do, is spend my life loving you. So, Kurt Hummel, my amazing friend, my one true love, will you marry me?

Blaine

[to Finn] You know, I don't really know what's going to happen between us, but I know that you used to be the guy that would make me feel like the most special girl in the whole world, and it doesn't feel that way anymore. Now it just feels sad and confusing. And the worst part is that it doesn't even feel that bad anymore.
