Why did you leave so abruptly in the middle of the night? Did you think I wouldn't notice you slip away like that? You left without so much as a note on my pillow. I'm hurt.
I can't think straight without you. People say I get a little (very) cranky whenever you leave like this. I become delirious. And no matter what I try, my mind just wanders back to thoughts of you. Truth be told, I need you too much to lose you again. Please come back tonight.
I'll straighten up the place. I'll make the bed. We can just talk if you'd like. I don't mean to sound dramatic, but I can't live without you. Believe me, I've tried. Medication, teas, therapy. Nothing worked to clear my head. You did.
I invite you lovingly, to come back into my open arms. My eyes will probably be a bit puffy and half-opened when you get back. Just don't be surprised when I sigh with relief at the sight of you.

Love,

Someone Who Misses You Dearly
