On 25 February 1891, Gissing married another working-class woman, Edith Alice Underwood. They settled in Exeter but moved to Brixton in June 1893 and Epsom in 1894. They had two children, Walter Leonard (1891–1916) and Alfred Charles Gissing (1896–1975), but the marriage was unsuccessful. Edith did not understand his work and Gissing insisted on keeping them socially isolated from his peers, which exacerbated the problems. Whereas Nell was too sick to complain about his controlling behaviour, some historians believe Edith stood up to him argumentatively. She may have suffered violent, uncontrolled rages as Gissing claimed in letters to Bertz, but the truth is elusive at this distance in time. Gissing took revenge (or acted to protect their older child from continual violent assaults, since he stated in letters his safety was in danger) in April 1896, when Walter was spirited away without Edith's knowledge and sent to stay with Gissing's sisters in Wakefield. Gissing pleaded Edith's violence, but he strongly disliked the way she presented him to his son. Alfred, the younger child, remained with his mother. The couple separated in 1897, though this was no clean break - Gissing spent time dodging Edith and afraid she might seek a reconciliation. In 1902, Edith was certified insane and confined to an asylum. At this time Gissing met and befriended Clara Collet who was probably in love with him, although it is unclear whether he reciprocated. They remained friends for the rest of his life and after his death she helped to support Edith and the children.
