Love letters can only hold weight when written as a letter. When sent as a text, they are a product to be consumed. They are delivered, and then opened, and then seen, and then she watches another reel, and then she replies with an emoji and a couple sentence fragments. Only when the full weight of your love is imposed upon her as a wall of ink upon parchment, delivered into her hands, opened by her hands, opened by her eyes, opening her eyes, into her head, opening her head, delivered into her head, delivered into her heart, opened by her heart, opening her heart, only then, only then, only then will she actually fucking mourn.
Only when all you are is ink upon paper left behind in a corner of her room, only THEN will she fucking mourn.
Ask me how I know.
