Sandie, I'm in almost the same boat.
Most years it is just me and DH. We can't have kids, so our family won't grow... it does get lonely for me (DH doesn't care, he likes being alone). All of my family is in Texas, and my in-law's don't "do" holidays much. They go camp in the desert and play.

I don't have any advice for you... but wanted to let you know you're not alone.

Sending you some happy thoughts and ((hugs)).
