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