David Barrett, 40, was reported to police on 7 September by a relative of the victim who said he had hurt her.
Officers visited the house where the pair lived and established Barrett had attacked the woman after an argument, grabbing her by the neck.
The argument stemmed from her doing something he did not agree with. The woman then disclosed a history of abuse, including Barrett being verbally abusive and strangling her on another occasion in July.
The woman had managed to secretly record videos of some of the abuse and take photos of her injuries.
Barrett, of Davis Place, Peterborough, was arrested but in a police interview denied all allegations.
He claimed the only time there was any physical violence was when he had pushed the woman away in self-defence.
However, when shown the videos of the abuse he agreed his behaviour was unacceptable.
Barrett was charged and appeared at Peterborough Crown Court where he admitted coercive control and two counts of intentional strangulation.
He was sentenced at the same court on Thursday (4 April) where he was handed a total of two years and six months in prison.
