How to know when you love him or her
Ask your friends for feedback.
When you love someone, immediately you want to introduce them to your friends. When you do introduce them, ask your friends for their honest opinions about your love interest.
Your friends might be able to be more objective than you and help you identify whether you seem in love or merely infatuated. It's important before embarking on a new relationship to have at least some approval from your friends.
