David Rathband had an affair with 7/7 survivor Lisa French in the months before he died which effectively ended their marriage, his widow told an inquest into his death.
Mrs Rathband told the inquest the officer could not understand why she would not take him back and rang her up to 100 times a day.
She visited him at his home on the evening he hanged himself and was concerned enough to call his welfare officer, Inspector John Heckles, and to text his sister in Staffordshire.
But, despite her fears, she did not consider he was going to kill himself, Kath Rathband told the hearing.
