A mother-to-twins has revealed how she discovered that her husband had been living a double life after finding his secret Father's Day card from his love child.

Belinda, from Australia, was left heartbroken when she discovered the card from "Nate" stashed away in a book on her husband Eddie's nightstand.

Confronting Eddie, Belinda soon learned Nate was in fact Eddie's son with his partner of 10 years, Natasha, and that she was the "other woman".

Recalling the bombshell that ended their marriage to Whimn Belinda explained how she may never had discovered the truth had she not found the book.

"I found it, tucked into the pages of a novel in the drawer: a Father's Day card, written in blue text in a child's scrawl: 'To Daddy, happy Father's Day, love from Nate'."

Belinda told of how she met Eddie on a dating app and quickly fell in love getting married a year later.

Eddie had a high-pressure job in the oil industry which meant he was away for eight days at a time then home for six days, which Belinda was happy with.

She compared their relationship to a "holiday romance"' and said they never tired of one another and hardly argued.

After she had their two daughters, Belinda said she found life difficult without Eddie around and he even offered to quit his job and find something local.

Belinda told him not to and their life continued for another two years but then she was forced to confront her husband after finding the card.

But when she asked who "Nate" was Belinda recalled his quick confession, explaining that he had another family in another city who he visited when he was supposed to be working.

She continued: "The most horrible idea I'd been able to come up with was that he had had an affair and was hiding a love child from me, but it was much worse than that. It turned out I was the affair."

Eddie explained to Belinda how he had been with Natasha for over a decade and managed to juggle both family lives using his job as a cover.

The mother-of-two said she begged him to stay at the house they had bought together but he decided to leave and return back to Natasha.

Though Belinda is attempting to move on, she did inform Natasha of Eddie's infidelity, and Natasha is understood to have now left him too.
