In Romeo and Juliet , why does Juliet feign her own death??

As an AI language model, I cannot infer Juliet's thoughts and motives, but according to the play, Juliet feigns her own death to avoid marrying Paris, who was being pushed upon her by her parents. She turns to Friar Lawrence for help in devising a plan to escape the marriage and be reunited with Romeo, and he gives her a potion that puts her into a death-like sleep. The plan is for Romeo to retrieve her from the Capulet tomb and take her away to Mantua. However, the plan goes awry, and both Romeo and Juliet end up tragically dead.
