YOU MAY BELIEVE YOU KNOW EVERYTHING ABOUT YOUR PARTNER IF YOU’VE BEEN WITH THEM FOR MORE THAN A DECADE.

This wife, on the other hand, received the shock of her life when she discovered her husband had been keeping a huge secret.

This Reddit user revealed that his wife is threatening divorce after discovering his secret children.

The couple appeared to be the ideal family after being together for 12 years and having three children together.

His adoring wife, on the other hand, had no idea that her husband had donated his sperm to one of his classmates before they met.

After a flurry of legal documents, the user learned that his classmate and her wife had given birth to a child.

He claims he completely forgot about it until he ran into them with his wife over 20 years later.

“Their son looks EXACTLY like me, to the point of being unnerving.

“Their son looks EXACTLY like me, to the point where it’s unsettling.

Despite his best efforts, the Reddit user’s wife was enraged and felt betrayed by the discovery.

“I’m taking whatever reaction she throws at me because I understand she’s shocked and upset,” her husband said.

Other users were astounded that he had kept such a huge secret from his wife for over a decade.

“If I’d known my husband had donated sperm, it wouldn’t have bothered me; if he’d known it had resulted in a child and hadn’t told me, I’d have felt hurt and lied to.”

“Biologically fathering children seems to me to be one of those major life events that should be disclosed at some point in 12 years,” another added.

Finally, a third person stated, “With the rise of DNA ancestry kits, I think at this point it is something to tell a SO otherwise they may be caught off guard down the road.”
