How do you know when someone truly loves you?

Um... you don't? Although I guess the socially acceptable answer is "You just know, it's like finding the missing half of your soul" or some skit like that. Honestly, I think we ALWAYS feel like that, until we get over that person. Rude, and unromantic I know, but it's the hormones talking, exactly like withdrawal from drug when they don't seem to be there. But how do you know the other person REALLY feels that way? Well if you're already feeling that way, you can't, but it's probably even easier to fake on clear head than it's to get it across while you're head over heels for them.
