About Sleeping with My Boyfriend's Brother

After dating for half a year, her boyfriend Bai Yueguang sent him a message: "I broke up." I was using his mobile phone to order food. I hesitated for two seconds and said, "How about I quit?" My boyfriend touched my head affectionately: "What are you talking about?" But that night he took her home, held her in his arms and listened to her cry all night. In a rage, I got angry and opened a bottle of 24-year-old Snow Beer at home to drown my sorrows. Just wake up—— Can anyone explain to me why my boyfriend's best friend is sleeping next to me? Purpose: Love others first, love yourself first
