I do know a few families with adult children who live in the same road, and can't seem to pull themselves away from their mum. It's nice to have a close mother/daughter relationship, but without exception, the adult women who live really close to their mother have really co-dependent relationships with really needy mothers, (and the adult daughters become needy and dependent too...) Sometimes it's sons as well as daughters...) But it's daughters moreso... And they see each other every single day (like spend 1-2 hours a day together, not just 'in passing.') They are never encouraged to go to University, or travel, or leave the area.
A few families I know (like this) all live within 10 minutes walk of one another. Parents, grandparents, siblings, their children, their cousins and aunts and uncles, the grandchildren etc... It's so weird and very insular. They very rarely have any friends, it's just this intense, very close extended family dynamic, with a matriarch who is usually 55-60+, who is mortified at the thought of ANY of them moving any further than 1 mile away.
On the rare occasion any of them have the courage to leave the area, they are pushed out, and rarely included in anything.
My 2 DC (both in their early 30s,) live around 15-20 miles away, and that's fine with me - and them!
