On the Wedding Night, He Stayed with His Best Friend's Wife, but When I Asked for a Divorce, He Broke His Guard

I am an obstetrician, but my husband is the "family member" of another pregnant woman in the ward. He was with her on my birthday, and even on my wedding day. The whole hospital was enjoying their CP, and I, the real wife, became a complete joke. I took off my wedding ring and threw the divorce agreement in front of Pei Shuhan. He frowned: "Can't you be more sensible?" "She is just the wife of a comrade in arms. Do you have to care about her like this?" I smiled: "Pei Shuhan, from today on, you are free."
