A father's every day conversation with his young daughter exposed his wife's cheating and shattered their 14-year marriage.

Steven (not his real name) returned home one day and listened as his daughter told him about her day, but one detail of her story stood out.

The girl mentioned that her mum had been at the neighbour's house. Her dad asked more questions and the girl recounted that when she arrived home from school she found her mum was not there, but instead the neighbour popped his head round his front door and told her that her mum would "be right out".

Alarm bells started ringing for Steven, who said he asked his wife why she had been with their neighbour the following day, Kidspot reports.

At first, she passed it off as nothing and came up with a quick excuse, but her husband said due to the length of time they had been together, he knew exactly how she acted when she was lying.

She eventually broke down and admitted that they had kissed and touched, but that it "felt wrong" so she stopped it.

Steve said: "I know how she lies to everybody, and how good she is at it. So I believe that it went further than the kissing."

He says he kicked her out of the house but later agreed to marriage counseling and allowing her to move back in, which he said he did "more for the kids".

Steve said the discovery has affected their relationship.

He said: "I'm literally going crazy because I do love her but it's starting to feel like love you have for a longtime friend and not a love you feel for your wife."

The man took to Reddit to ask for advice.

One Reddit user said: "I think at this point you have to assume she did cheat on you and then ask yourself whether you can forgive her.

"Figure out what it will take for you to be able to stay with your wife and not be thinking about what happened in ways that interferes with you and your family’s well being. It will take time."
