you are not - you're seeing results and doing great things. Confrontation also didn't really work in my experience - but everytime he choses you over her and says I love is a shovel full of dirt in the grave of the side stuff he has going on. . You just have to get her good and buried first. (I do not condone or suggest literal murder!)
