My husband and I have been full-time almost 8 yrs, but are currently on our first trip west. Other trips were following the warm weather, but usually 1,000 miles or less. We are both tired on this trip and looking forward to arriving in Phoenix and being able to sit for awhile. Maybe just take a break for a couple months and then suggest a weekend closer destination. See how she feels about that. If she doesn't even want to do that, then you have a decision to make. I have a feeling you wouldn't be happy traveling by yourself though. Have met guys who lost their wives and it was a few years before they were comfortable traveling alone.
