Marriage Strain

Not what you think. We're getting along fine. The problem is that we never see each other. Peter works long hours and some nights and weekends; I take most meals with the kids, manage them without him, and must go to bed not long after he gets home because I need more sleep than he does. He is more absentminded than he wishes he were, and I scold more than I wish I did, but our affection has not been diminished by parenting--if anything, it's been strengthened. We're just sad that we don't have the time or energy to show it. Lately, we've been getting out alone together maybe once every couple of months. We've had privacy, time, and energy at home all at the same time very seldom. I miss the man I married.

I have read a bit about marriage changes during the early parenting years, but of course all I can find is about parenting from birth, not parenting from the age of mobility-but-no-sense. Anyone out there, are you aware of anything we might read about marriage changes during older child adoptive parenting?
