My triangulation came when I tried to end the relationship. He simply went out, got a vulnerable woman and led her up the garden path then tried to rub my nose in it. This was after decades of marriage and while he was begging for another chance. Looking back it was so obvious. He would tell me how much she thought of him. How handsome and charismatic she would say he was. How much younger than me she was. All this while we were still together. Not even subtle.
