If you love someone because you think that he or she is really gorgeous ….then it's not love .. it's “Infatuation”

If you love someone because you think that you shouldn't leave him because others think that you shouldn't … then it's not love.. it's “Compromise”

If you love someone because you have been kissed by him … then it's not love.. it's “Inferiority complex”

If you love someone because you cannot leave him thinking that it would hurt his feelings .. then it's not love .. it's “Charity”

If you love someone because you share every thing with him … then it's not love… it's “Friendship”

BUT…
If you feel the pain of the other person more than him even when he is stable and you cry for him … that's “LOVE”

If you get attracted to other people but stay with him without any regrets… that's “LOVE”

If you let him go knowing that he has to go even though you don't want to … that's “LOVE”..
