You cannot force your importance in someone's life. You can just love them , truly ,and purely. Just because someone means a great deal in your life , doesn't make it the same for you. You may or may not be . But Trying to make someone , to give you equal love , forcefully, is definitely not love my dear.
That's just seeking attention , not a place in heart.
Attention can be distracted ,
Hearts are imprinted forever.
