its very easy to know when you are in love, when you are really in love you don't see any fault with the one you love so much, even when others are complaining bitterly about the person.
Secondly, when you are in love with someone, you want to spend 24 hours of the day with the person.
When you are in love you lavish the person with gifts even when its not convenient to do so.
