It's clear to see that you don't know her worth.
Sometimes you don't even know you've hurt her. she's sensitive and fragile and yet you still hurt her. She gave you her heart and asked you to take care of it, but what did you do? you just left it somewhere else to be covered in dust.
You took her for granted and she knew that, but still she didn't leave you. How could she? You're all she ever had, you were her lifeline, her light in the dark. She couldn't leave and she wouldn't leave you, because you know why? she knows you're like her but the difference is that she knows your worth and she wouldn't let anyone hurt you the way you hurt her.
She'll sacrifice her happiness for yours. she pretends she's okay but really, you broke her into pieces and the saddest part is: she still gave you the remnants and loved you whole. She cried every night as you we're sound as sleep, overwhelmed by her dark thoughts, drowning in her own tears because she couldn't help but overthink and as morning came, she smiled and hoped this day would be better than the others.
Boy, remember even the most beautiful flower withers if not treated correctly, same as feelings, same as love.
Treat her better and know her worth.
