Perfect response Carol. My wife and I figured out long ago (we celebrate our 20th in March) that we love our kids more than life, but they WILL grow up and leave the nest and when that happens we don't want to look at each other and say "who are you?" A marriage is like a garden, it takes constant care to make it grow.
We have taken at least one trip a year with out our 2 boys. They might have given us that guilt trip before we left, but they have discovered what wonderful people their grandparents and aunts and uncles are. Now grandma (and grandpa too before he passed) and the uncles are some of their best friends.
Carol, you hit it right on the head, what better example can you give your kids than loving, devoted parents? Our kids know we love them without question and they know my wife and I love each other without question, so if a few days a year are needed to recharge those batteries, it's a small price to pay.
Sorry to get sentimental, but we feel very strongly, if you don't love your spouse and yourself, how will your children know how to love?
