ER, Season 4

Carol (to Doug):
I've spent years, years of my life, changing to fit your needs, working around your schedule, your insecurities, your inability to commit. Well, you know what, Doug? It's not all about you! I know that may come as a shock, but a relationship is give and take; two people as equals, and right now I need something! So you can grow up and accept it or you can go on being the same selfish, self-centered bastard you've always been and refuse to give me the one thing, the one thing I've ever asked you for!
