I miss sleeping next to you -

A great way to say goodnight to your girl friend, remind her that you miss her and not just for obvious reasons ;) Throw her off her game by explaining that you miss sleeping next to her as then you'll miss her calm, sleeping face next to you in the morning; you'll miss the way she struggles to steal the entire blanket while rolling around in her sleep; you'll miss the way you hold and cuddle her while she sleeps to the rhythm of your heartbeat. Trust me, she'll march in through that door with that pillow and blanket to be next to you.
