In the tudors why didn't king henry like mary booleyn anymore?

King Henry VIII's interest in Mary Boleyn waned as he became more infatuated with her sister, Anne Boleyn. While Mary was initially a mistress to Henry, the political and personal ambitions surrounding Anne, including her potential to bear a male heir, drew Henry's attention away from Mary. Additionally, societal expectations and the need for a legitimate marriage further complicated Henry's relationship with Mary, leading to her diminishing influence at court.
