Thank You, Redpepper.
We three had lived in the same city, and had all but lived together in terms of belongings and possessions for many months before we started this recent long-distance portion of our relationship. There are no kids for any of us.
That's a good question to ask--about cohabitation. And I'd never thought about it or questioned it like that before. But I will certainly have to give it some thought now--as to what makes us want that, and why.
