If you're looking for the word that means caring about someone beyond all rationality and wanting them to have everything they want, no matter how much it destroys you, it's love! And when you love somone, 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 some other disposable thing that is not worth fighting for. - Ted Mosby
