Glee Quotes

[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.

Rachel

I just want somebody to love me.
