DH and I retired in our 50s. We then started RVing and myGod did we have wonderful times!!! Each of those trips lives in my memory like dreams come true. We even RV'd cross country 4 times to go to Disney in Florida (yes, I'm one of 'those adults'). RVing is not something I could ever do on my own, I don't have the physical strength at this point. So, those trips are as dead as the dodo. But I have my memories and I refuse to allow them to be 'tainted' by the reason I can no longer do them.
We've always also done 'our own thing' once the DSs were grown. He did trips to pursue his sport, I went to Disney (CA) yearly with my 'Disney BFF' and went to visit my cousin/BFF every year. I plan to keep those trips going. And my brother and I are tentatively planning a trip to the UK in about 3 years. He's been, I never have. He wants to show me the place in Cornwall where our paternal grandparents (and many generations before them) lived.
At this point my 'hold up' is the dog. He's 13 and has never been boarded. I simply can't do that to him at his age plus he's had enough upheaval with the shit that's gone on. So travels will have to wait until 'in the fullness of time' he's no longer with me. It's one of the things I'm most furious with DH about. It was actually mostly DH's dog as the dog 'tagged' DH as 'his person' pretty much right away. But DH isn't capable of caring for him due to his drinking.
