I relate to that.
It's like this, I want to keep on feeling like they want me and can't live without me. (They act like they will marry you if they think they can get laid.)
If I go to sleep and wake up next to them I have to wonder how they will react when they get up later. Will he think I am ugly and he had total beer goggles on? Will he just think I'm a slut?
And mostly I don't want to feel like he only used me for sex. If I'm around when it's time for him to take the "walk of shame", how shameful will he be? Is he going to regret it? Is he going to act like my house has the plague and he hopes he never crosses my path again?

I have had so many guys be aloof, rude, and mean after a one night stand and that hurts worse than anything. If I knew they would just kiss me and say they will miss me, and actually pretend to mean it (they don't really have to mean it, just act like it) then I might be more inclined to sleep the night through with them rather than try to sneak out afterwards.
