The former Blue Peter host is said to be debating the future of her 11-year marriage following accusations that Bovey cheated while she was away working in Canada.
A source in Turner's family has since claimed that the 52-year-old may now seize the opportunity to kickstart her career.
"[She is] far too hurt," they told The Mirror. "I can't see a chance of her asking him back. A lot of friends think this will be the end.
"She sacrificed a lot in her career for family. The time may be right for her to concentrate on it again."
Bovey has denied allegations of his infidelity.
