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 someone, you don’t stop ever. Even when people roll their eyes or call you crazy, even then, especially then, you don’t give up. Because if you could give up, if you could take the whole world advice and move on and find someone else, that wouldn’t be love. That will be some other disposable thing that it’s not worth fighting for.
