Family is Emotional Closeness
If two people live together, that doesn't mean they are a family. And if there are children, that still doesn't make the two a family. Stamps in passports even less so. Emotional closeness makes a couple a family. If it's not there, a man and a woman can live together under one roof for years, raise children, host guests and relatives, visit each other, give each other gifts, sometimes even travel with the whole family, but still NOT be a family. They are just lonely cohabitants who live parallel lives in parallel universes. Staying in such relationships, comforting oneself with the thought that it is supposedly convenient and comfortable, means living life in vain. Because that convenience and comfort is the convenience of a grave.
