how did betty gore find out about the affair

Betty Gore is widely reported to have found out about the affair when Candy Montgomery came to her house on June 13, 1980, and Betty directly confronted her, revealing she already knew about Candy’s relationship with Allan Gore.

The Confrontation

Most detailed accounts describe that Candy stopped by the Gore home that morning, supposedly for a routine errand connected to the children, when the conversation turned tense. At that point, Betty told Candy she knew about the affair with Allan, shifting the visit from casual to confrontational.

How She Knew

Sources based on court testimony and Texas Monthly’s reporting say Betty had physical proof: she had kept or seen letters and cards exchanged between Candy and Allan that made the affair obvious. When Candy first tried to deny it, Betty is said to have produced this evidence, forcing Candy to admit the relationship had existed but was now over.

What Is Confirmed vs. Inferred

What is solidly documented is that by the day of the murder, Betty already knew about the affair and directly confronted Candy about it in her home. The exact moment Betty first suspected or discovered the relationship (before that confrontation) is less clearly recorded in public sources, but the letters/cards detail is repeatedly cited as the way she confirmed her suspicions.
