She doesn't know how much he cares about her.
She doesn't know how much he misses all the times they spent together when they were younger.
She doesn't know much he thinks about her everyday and how it makes him smile.
She doesn't know how much he wishes he could hold her in his arms every day and every night.
She doesn't how much he wants to pull her close and kiss her like it's the last thing he will ever do
and last but not least She doesn't know how much he wants to tell her the three words he has kept bottled up inside for so long but is to afraid to say them because he already knows how things would go he knows that she doesn't love him back and that them being together could never be so.
