In Lagos there are many SOWs and not only because of any childhood issues, but for economic reasons. Married and older men are wealthier. When they find a richer man, they move.
I think you can confront the other woman, you can lose your cool, you can show fear. If you fail to show any emotions, you may implode. I have been married almost a decade, I confronted my husbands, new ‘business partner’ friend who didnt respect boundaries ( long story), then I called my friends and we laughed about it. But it’s weird that it gave me peace. Craziest call of my life, I almost chickened out of it. I think people should do what makes them happy show your emotions or not, its up to you.
