Quah Tee Keon painted himself as a victim of adultery, who had to support his wife and her lover.
He had met his wife, Ms Loong Mei Ling, 33, in 2001 when they were working together.
They started dating and got married after three years. According to Registry of Marriages records, they married on May 12, 2004.
Quah claimed that he found out his wife was cheating on him soon after they got married, but he did not know who the man was.
He was planning to divorce her after selling their HDB flat when the five-year minimum occupation period was up.
In July, Ms Loong wanted to rent a room in their flat to a colleague, Mr Ruan Chao Kiang, 32. Quah then suspected that his wife was having an affair with the Chinese national.
He claimed that his wife was materialistic and tried to seduce Mr Ruan after she found out that he was rich.
He also claimed that his wife charged Mr Ruan only $50 a month for rent and then sent him $480 a week after he was sent back to China when he lost his job following Quah's complaint about him to the company.
Ms Loong had also asked him to drive Mr Ruan to work in his taxi, said Quah.
It was previously reported that Ms Loong had returned to their Pahang home a month ago because she wanted to escape from her husband's beatings.
He had also demanded money from her to support his gambling habit.
But Quah disputed these claims, saying that his wife, who earned $1,000 a month, had no money to lend him. He also claimed that he had diabetes and couldn't possibly attack her because he suffered from cramps.
