This is sad for the real wife and kids, not the ‘second wife’
Many males are stupid in a way other male animals are not. The excuse that sex is too sweet or a woman is too hot that you can only act stupid is lame and doesn’t hold water.
But kila mtu anavuns kile amepanda, that’s why God in his own wisdom says death and adultery are the 2 instances married couples can break the relationship, so it’s the man’s loss.
