Kenyan wives need to stop being delusional. I empathise with the pain of being married to a cheating spouse but threatening side chics with Karma is the weakest move I have ever seen. Karma does not exist. It is an imaginary thing losers evoke to feel better about themselves, and their failure to exert vengeance against those who hurt them.
Even if Karma is a thing, I hope one day Kenyan wives will realise that Karma is not when something bad happens to the other woman. Your husband will still find another and when something bad happens to her too, he will find another one. Single women are always going to be there. You cannot wish them away and even if it was possible, wishing them away is not Karma.
