In 2018, a wife found out her husband was cheating on her.
She placed a tracking device on her husband's car as well as the mistress's car.
She even sewed in listening devices into his clothes.
In April of 2018, the wife broke into the mistress's home killing her before taking her own life.
In a 20/20 episode airing this Friday, the husband, Mark, says that he, broke her heart. My regret comes back to making her feel like she had no other choice.
Have you ever caught your significant other cheating on you or have you been caught cheating? What happened?
