CEO's Sweet Love:Arranged Marriage

After three years, he came back with his mistress, and I heard him talking about divorce. He did not say anything despite taking my innocence before leaving. I was deeply hurt. He never gave me a chance to be an effective wife to him, and yet he wanted to divorce me. It's not that I love him; it's just that I thought I had been loyal to him while he enjoyed himself with his mistress. Yet he dares to complain as if I had him on his neck.
I was furious. I would ensure that he and his mistress had difficulty convincing me of the divorce. But why was he acting differently?
