Love is such a personal feeling. It is not about what we feel towards others. It is just how we feel inside our hearts. Then why do we say "I love u" to someone else?
Love is being good and feeling good. That is why I say love starts from oneself. We like all those who make us feel good and be good. In other words, we love them. So when we say "I love you", it means we feel good being with them.
Love is nothing but goodness. When goodness is there is our hearts, love will never leave us.
Be good. Do good. Feel good. Stay loving for ever.
