How do i know if im in love?

everyone is different, and you have to find out what that is for you. You can find this out by when you really like someone you think you love, and then you'll get that feeling and you'll know. One of my friends right leg falls asleep when she fell in love, or would be around the guy she loved. Or it doesn't have to be a physical feeling. One of my friends would constantly go running when she was in love, to let that "cloud nine" feeling run off. Or another would write a poem everyday when he was trying to get the girl, and his poetry was about how he felt everyday, or it would be about her. Yours may be your heart racing, but that could be you just being nervous around her. Just pay attention to your actionns and feelings
