I have great trouble getting to sleep when my husband's away, because part of me seems to insist on waiting up for him. I KNOW when he's coming home, and I KNOW it's not tonight, and I tell myself over and over that he won't be back until X date, so just go to sleep, but some irrational part of me still wants to wait up for him.

Anyway, I know how it is. It seems to be part of being married, if you have a really close bond with your partner. I'm willing to pay this price for the delight of the really close bond. :-)
