why did justin and selena break up

Justin Bieber and Selena Gomez broke up primarily due to trust issues, jealousy, and their conflicting lifestyles. One reported triggering incident involved Justin casting actress Chanel Celaya in his music video and sending her secret, sexually toned text messages, which caused Selena to lose trust and get angry when Justin denied wrongdoing. Their busy and conflicting work schedules also contributed to their on-again, off-again dynamic. Over time, differences in life goals, rumors of infidelity, mental health struggles, and the pressure of fame further strained their relationship. They ultimately broke up permanently in 2018, with Selena focusing on her own health and happiness, and Justin later marrying Hailey Baldwin (now Bieber).
