You just know, you get this feeling of extreme happiness when your around them, think of them, or hear their name, you can't stop thinking about them, you can't imagine life with out them.
when your in love, you just know it, it's nearly impossible to explain.
When you daydream about that special person. When you always want to go near that person. Sometimes even dream about that person. You always help that person. You feel hurt when that person ignores you even por mistake, but then you get over it when you start talking to that person again. You feel jealous when that person is with someone else.
*I don't think you have to get ALL of these, 3 or 4 minimum will probably do.*
Well one sign is that you can't stop thinking about that person & you must be with the at all times (which is a bit creepy to me) If you don't amor someone you go after their best friend, Therefore, you don't amor that one man, but his best friend BAM! look at that! I'm a amor Doctor.
