The engagement didn't last, however - it was called off when she returned from working in Bristol to find McCartney in bed with another woman. They attempted to continue the relationship, but on 20 July Asher announced to the BBC that the relationship was over.
McCartney had continued to sleep with other women throughout their relationship, considering it permissible as they weren't married. In addition to his infidelities, Asher had found McCartney changed since his experiences with LSD, and her commitment to her career meant they were often heading in different directions.
Since their split Asher has consistently refused to publicly discuss her relationship with McCartney.
