Yes but I think we do that. The street I live in eg, is the street I have lived in since I got married. We bought our house when we were 23 and 24 but weren't "allowed" to move into it until we got married 3 months later (catholic).
Can't believe we put up with it now but it doesn't matter, we're still in it.
AND the people who were here in this street when we bought it and then moved in, are about 80% of the people who still live here plus some of their (now grown up) children with their own families.
I swear the only people who aren't here now are people who passed away and their children are in their houses.
So this would look like the norm to me. Plus there was a house two doors down up for sale last week. My son sent it to me and said him and his fiancee were thinking of buying it, but they were off on holiday that night.
It was sold a day later so that was that.
But every single family in this street are long term married so that, to me, is the norm. My family are the same.
However, I have friends who have been divorced, some remarried, some single, but also couple friends that my huband and I have known since we were 18/30 say who are still together.
It's all anecdotal really.
I just think 23 isn't that young!
