I live in a different country now and it's difficult to maintain long distance relationships in the best circumstances. When I lived there and saw them on the street (I lived nearby) it was always nice and they are wonderful people, but there was no way to have a relationship beyond that as my ex, the replacement relationship, and child that followed, were their family then, not me. It's always in the back of my mind as I adored the family and they treated me like one of them. It's just how it goes.
