One in five women have dumped their partner because of their web or gaming habits, says MyVoucherCodes.
Research by the UK online discount site revealed that 80 per cent of women claim their other half spends too much time playing computer games or browsing the web.
Furthermore, 70 per cent said the gaming addiction was the cause of arguments between the couple.
MyVoucherCodes said Call of Duty was rated the game most likely to start a row between a couple.
When it came to women, 72 per cent of men said they thought their partner spent too much time on the internet, but only six percent saw this as a reason to end the relationship.
"I'm no relationship expert, but it seems that as technology improves, our ability to interact with those around us lessens - hopefully these statistics will be the push people need to reassess the way they treat loved ones."said MyVoucherCodes managing director Mark Pearson.
