Preferring to stay at home

I think that we are all different!

I believe once we are retired (if you are) and our own children are “off our hands” (in a good way), you should live your life exactly as you wish!

Nothing wrong with you at all

I agree, I hate flying, but made the effort when the children were at home, and as they are all spaced out, that was a lot of holidays.
To be fair, we had some wonderful times, really great memories, but when the last one flew the nest, I said I was done with flying.
I’m occasionally tempted, especially when my grandchildren nag at me, never say never, but I don’t think I could face it all.

DH and I used to have lovely holidays abroad in Europe and even America as well as sea and river cruises. I would so much love to do these again but both our energy levels are low as we’ve both had health issues and even a few days away in this country wipes us out so, I’m afraid, that ship has sailed - sigh 😢

I think many of us become less inclined to travel as we get older,especially if you have travelled widely in the past. I haven't been abroad for years, though never travelled a lot anyway. I still like day trips to the coast but will only do trips that are staightforward and not too long. Long journeys are tiring. I get more anxious about travelling these days, which I think is common.

There's nothing wrong with you. We are all different and if you are happier at home then that is just fine.
I'm just starting to feel that way too as I'm getting pretty old now. But I've just come back from a holiday abroad with one of my granddaughters and it was wonderful. I'm glad I made the effort.
However, it's lovely that you are so content at home, so don't feel under any pressure to venture forth if you don't want to.
It's your choice.
