But none of that is new! Sure, the divorce rates were lower in the past, and more infidelities, out of wedlock pregnancies etc were covered up, but the shagging around is as old as time. As amply demonstrated by people tracing their family tree and/or using DNA databases.
In my own family alone, my grandfather discovered in late middle age he was the result of a bigamous marriage and that the ‘sailor’ father he barely knew had at least one other wife and family, and, on the other side of the family, the baby (stillborn) with which my grandmother was pregnant when she married my grandfather wasn’t his child but that of a married neighbour.
A great-uncle of mine emigrated to the US in the 30s, with the plan that he’d send the fares for his wife and children once he’d settled and found work. Never heard from again, it was assumed he’d died, until a letter arrived twenty years later from his widowed second wife in Wisconsin asking his parents for financial help. She had some idea there had been another family at home, and I don’t think it was all that unusual.
A friend discovered in the late nineties that the woman she’d grown up thinking of as her mother was in fact her grandmother, and her eldest ‘sister’ was her mother.
Another friend, showed his parents his very warts and all memoir about growing up gay in smalltown Ireland before its publication. His eightysomething mother was absolutely fine with all the gay sex. The only thing she asked him to conceal was the fact that her own parents had separated discreetly in the 1950s, and her father had, no divorce being possible, lived with another woman in the same small town, while showing up to go to mass with his wife and children on Sundays.
It’s not new.
