The other word for love

-I can tell she did her hair for him-

Her: Oh man!(her eyes light up) I can't wait to see him tonight! He's amazing! The best! I love him!
Me: Ooooohhhwow! Haha
Her: Whoah, I didn't mean it like that....I mean.....
Me: There should be another word for that kind of love actually. Like a word for the feeling(I make a centre body fluttery motion with my hand) where you want to see the person all the time and know everything about them and can't wait to hear from them and you like everything about them
