During the three-day inquest into the death of Pc David Rathband, at Newcastle's Moot Hall, the court heard of his affairs, one with 7/7 London bombing survivor Lisa French.
Mrs Rathband told David Rathband the marriage was over prior to him going to Australia with his identical twin Darren.
"For someone to say that, I just thought it was an awful thing to say.
"I was concerned for his well-being and his mental state but I did not think he would kill himself."
While on holiday, Mr Rathband tried to contact his wife up to 50 times a day. In one call he pretended to be a police officer saying her husband was dead.
Mrs Rathband visited him for the last time on the night he died. She contacted his sister Debbie Essery and his welfare officer Insp John Heckles.
That evening, officers broke into his home and found him hanging.
Ms French had also seen him earlier that day, and she told the inquest he said he had experienced suicidal thoughts, but had not been able to kill himself.
