Nigerian activist, Comrade Israel Joe, has taken to Facebook to advise men.
He urged them to stop disturbing their married ex-girlfriends.
According to Joe, if they loved their ex-girlfriends that much, they should have gotten married.
He also urged ladies to cut ties with their ex after marriage.
"A lot of you guys out there should leave your ex-girlfriends who are married alone. Stop telling them about the memories of your relationship. She needs to focus on her marriage and love her new boyfriend who is now her husband. If you loved her that much, you would have married her. What you didn't value then is now another man's treasure. Na another tin you dey find becos u know her weak point. Ladies sef should cut such people off if dem want make their marriage contain dem," he wrote in a Facebook post on Wednesday.
