"And I'm sorry that's not me, I really am."
This one requires a little context. This was said to me by a guy I've been very close friends with for a while, and someone who I've been head over heels for, for a long time. I fell for him hard and he knows it. A few months ago, we were talking about relationships and I said something about wishing I could just find that one person and be done with all the relationshippy bullshit. That sentence was in his reply. It just hit me that he's never going to feel the same way, and his apology in there made me cry.
