Is it normal to feel slightly guilty leaving the kids behind for a week-long vacation with my husband?

This year, my husband and I are celebrating our 20th wedding anniversary, so we wanted to plan a relaxing vacation for just the two of us. When we started poking around online looking into all-inclusive vacations in the Caribbean, most of the resorts we really liked were "kid-free."

And that didn't sound like a bad idea for us. We so need a couples-only vacation together. The last time we went away together without the kids was right before we had our first son 15 years ago. I mean, come on!

So we booked our amazing trip without feeling guilty about not including the kids. We made sure we had a week-long family vacation with them this summer, and it was a ton of fun. And now as we get closer to our trip to Jamaica, I'm feeling a little bit... guilty?

Maybe it's because it's summertime and I know they'll be less occupied versus when they are in school, or maybe it's the sad face my youngest son gave me the other day when we were talking about our trip.

I don't know for sure why, but I'm feeling a little uneasy. Is it normal that I'm feeling this way?
