A mother of two Jayne Mown has pleaded for an advice after discovering that her ex- husband  Fred, 56, and daughter are in sexual relationship.

The devastated woman sought help from fellow Mums net users with a post that has since been deleted.

Here she expressed concerns about whether or not the relationship should be considered moral incest.

Sharing her story, the mum explained that she’d had her first child when she was very young and went on to marry her ex-partner when her daughter was just 11-years –old.

Though he never legally adopted her, the man raised her daughter as his own.

She even changed her surname to her stepfather’s and called him ‘dad’ for more than 20 years.

What’s more now the daughter has a young son of her own who refers to him as ‘pappy’- as in grandfather.

“it just feels so wrong on every level.’ She wrote.

“I know biologically it’s not incest but morally it feels like it. I’m in total shock and haven’t been able speaking to them since.”

Horrified by her story, other Mums net users rallied round to comfort the distressed woman but voiced their concerns about when the relationship started.

Less shocked, other women came forward to reveal that while this woman’s story is appalling, it’s a situation not unheard of.

“I’m horrified to admit that I know someone who left his wife for her daughter after he had raised her as a stepdaughter from the age of two,” one woman confessed.
