(LifeWire) — Elizabeth Blackney says her heart goes out to Elizabeth Edwards, wife of former Democratic presidential hopeful Sen. John Edwards, because she’s been there, too.

Expert says some people cheat only once and never cheat again.

Blackney was just 22 and pregnant when she found out in 1995 her husband had been having an extramarital affair.

“It occurred to me that I hadn’t seen the phone bill come in the mail for a while,” says the now 36-year-old mother in Bend, Oregon. A quick call to the phone company confirmed that her husband had requested the bills be sent to a post office box that she was unaware of.

After Blackney had the bills rerouted to their home address, she discovered what he was hiding: a long-distance relationship with another woman. When Blackney called the woman’s number to investigate, she found out that her husband not only had a mistress, but that he’d told the other woman that Blackney had died in childbirth.
