John G, from North Pennsylvania, who has filed for divorce, has opened up on the moment he realised his wife was ‘throwing away’ 18 years of marriage.
After becoming suspicious, he used a drone to follow his wife Donna on her walk to work, only to capture her meeting up with a man and getting into his car.
He later published the footage to YouTube.
Speaking exclusively to MailOnline, John admitted his initial anger was targeted at the unknown man, saying he thought he was going to kill him for ruining his life.

The photographer, who asked to be identified only as John G to protect the identity of his children, said: “That day I didn’t want to know the details.
“But I was angry at him for some reason.
“I know he’s not the main person to blame in this situation, but I thought at that point I was going to kill him.
“He was the one who had ruined my life and I was going to kill him.
