Man's shock discovery after wife left Facebook open

A man in the US says he discovered his wife of 10 years was having multiple affairs after she left her Facebook open.

Seth Megow, 33, who write the blog 'Who put me iPad in the Dishwasher', says he thought he and wife Chrissy were happy together.

They met when he was 19 and he says the first eight years were great, but that his wife's behaviour then changed.

She became harder to communicate with, he says, and began going out at night.

Attempts to talk to her about her change in behaviour failed.

That's when Seth says he went into "detective mode" while his wife remained in "avoidance mode".

One evening, when Chrissy had left her Facebook open, Seth began reading through her messages and was shocked at what he discovered.

The George dad says he discovered his wife was having multiple affairs and at least one relationship was long-term.

"It was in that moment, I realized the extent of it all," he says. "There were multiple affairs happening."

Doing his best to make sense of the situation, Seth says he believed his wife may be suffering from postpartum depression.

"My best guess about it all was she suffered from postpartum depression and struggled with some slight substance abuse, which led to an initial affair," he says.

The couple have four children - Stevie, Neela, Titus and Olive. They have since divorced and are focusing on co-parenting.

Seth has re-partnered and now blogs about single parenthood.
