Newington Green, North London 1797:
"After their marriage, they moved into two adjoining houses, known as The Polygon, so that they could both still retain their independence; they often communicated by letter. By all accounts, theirs was a happy and stable, relationship".
That was Ms Mary Wollestonecraft and Mr William Godwin. Granted they were of a dissenting nature anyway, but it worked for them romantically.
Like-wise, Tim Burton & Helena Bottom Carter.
And Woody Allen and Mia Farrow - however, it could be argued it just gave him more space to get it on with their daughter . . .
I quite like the idea of us living 'together' as couples across the way, over the road, next door, the flat above. Is this weird?*
*if it leads to you marrying your adopted daughter, obviously, yes.
