Gordon Park denies murdering his wife, Carol
Gordon Park, 60, told a jury at Manchester Crown Court of his devotion to wife Carol and how at first they were "love's young dream".
The retired teacher from Barrow denies murdering his wife, then 30, in 1976.
On Wednesday, at the start of the defence case, Mr Park said his wife lost her sparkle after having children.
Joie de vivre
Mr Park told how he met the young clerk while she was working at the local town hall around 1963.
He said: "I was in love with the girl, quite simply. It was wonderful. Love's young dream."
They married in 1967 but the relationship hit the rocks shortly after they adopted Mrs Park's sister's child and had their first baby, the court heard.
Asked about their relationship after the children arrived, Mr Park said: "I think it changed. I think having two young children in such a short time took a lot out of her.
"She had lost a lot of the sparkle that you have heard people talk about. The joie de vivre. The spontaneity."
Mrs Park's body was discovered by amateur scuba divers wrapped in bags and weighed down at the bottom of Coniston Water in Cumbria in 1997.
