The wife, known only as Amelia, said his addiction surpassed even his desire for sex and they only had intercourse once or twice a month since 2013 before parting ways a few months ago.
Amelia, 34, who lives in Selangor, had been granted custody of their three sons aged between four and eight, Metro Ahad reported.
The civil servant said her husband, who works as an engineer, admitted that playing games on his smartphone was better than being with her.
She became like a single mother to their sons as he was often engrossed in the games and neglected the family, she said, adding that he would even be abusive whenever he lost a game.
“He wasn’t so obsessed earlier in our marriage. But in 2012, his character started to change and he couldn’t stand being separated from his phone,” she said.
The situation became worse when he started competing with gamers around the world, sometimes coming to bed only at 4am, she said.
She said his “hobby” had begun as a teenager when he became interested in video games.
Despite numerous counselling sessions, Amelia said the situation did not improve and she had no choice but to pack her bags.
