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 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.

Listen, Morty, I hate to break it to you but what people call "love" is just a chemical reaction that compels animals to breed. It hits hard, Morty, then it slowly fades, leaving you stranded in a failing marriage. I did it. Your parents are gonna do it. Break the cycle, Morty. Rise above. Focus on science
Robert Fulghum
We are all a little weird and life’s a little weird, and when we find someone whose weirdness is compatible with ours, we join up with them and fall in mutual weirdness and call it love.
