"Actually, there is a word for that. It's love. I'm in love with her, okay? If you're looking for the word that means caring for someone beyond all rationality and wanting them to have everything they want no matter how much it destroys you, its love! And when you love someone you just don't stop. Ever.
When you love someone you just, you...you don't stop. Ever. Even when people roll their eyes or call you crazy. Even then. Especially then. You just- you don't give up because if I could give up... If I could just, you know, take the whole world's advice and- and move on and find someone else, that wouldn't be love. That would be... That would be some other disposable thing that is not worth fighting for. But that is not what this is." — Ted Mosby, How I Met Your Mother Season 9, Episode 17
