The man, identified as Ramadan, instantly collapsed in disbelief on the floor at an internet shop before coming round and rushing home to face his unfaithful wife.
The woman first denied his allegations and started to swear at him, prompting her husband to face her with the film.
Unable to deny it any more, she confessed to have betrayed him with her pre-marriage boy friend, telling him she had never loved him although they had four children during their 16-year marriage.
“I found 11 films showing my wife in indecent scenes with her lover….it was the first time I watched a indecent film and I did this just out of curiosity.
“She first denied it and accused me of being insane before I faced her with the films…she then confessed to be still in love with her boyfriend, saying he is as young as her and that I am an old man.”
Ramadan said he had been happy during his marriage life until he logged on to that website. Newspapers did not say whether he decided to divorce her.
