I'd agree, agnurse. It did happen in families in the past, but it just wasn't so obvious. My mother left her family in Canada and rarely spoke to her own mother for years at a time, and only ever went there to visit on one occasion . She never said she'd "gone no contact", she just didn't write to her family and they didn't write to her. With such limited methods of contact as we had in those days, nobody knew if you were in contact or not. We just know about it now because it's more obvious.
Another Great Expectations. Why?
