Edday Nderitu, the wife of Samidoh, has used social media, to be honest about the difficulties in her marriage.
She said in a lengthy essay that the past three years have been painful due to the Mugithi star's blatant humiliation of her.
Edday claimed that despite being faithful during difficult times, she is almost at her breaking point and has run out of things to say to God.
Did you read this?
"Our marriage has been exactly 15 years long, with ups and downs, humble beginnings where little was enough for us, and the last three years have been nothing but agony."
She said, "you've made me appear stupid and taken my quiet for granted, yet I've stuck with you through the contempt, humiliation, and online trolling."
Edday further declared that she would not raise her kids in a polygamous set-up, thus blaming Karen Nyamu (who has two babies with Samidoh) for ruining her home.
"I have supported you and helped you develop your skill, but I will not raise my children in a polygamous family, especially with a lady who is more than ten years my senior, has no morals, and has no regard for my family, or 'kimura Kia aba,' as you call it."
Edday acknowledged that her troubled marriage has been at the top of her prayer list and claimed that the ongoing humiliation and mockery had almost brought her to her breaking point.
You have dragged my kids and me into an ocean of pain; may you remember this day, she said. "I have asked God every day to give me strength to pray for you, but today I have nothing to say God about you," she said.
The incident happened after Nyamu posted pictures on social media showing her with Samidoh at a burial in Murang'a.
The Nominated Senator and Samidoh were pictured sitting close to one another and grinning for the cameras.
