Why Luzhin is single.

                    Part five of “Crime and Punishment’s” chapters’ focuses mainly on Marmeladov's funeral. Everyone in Marmeladov's building is invited to the funeral dinner (which Katerina spent most of Raskolinkov's money on). This includes Peter Luzhin, who is staying with Lebezyatnikov (the guy who beat Katerina). Luzhin is still reeling about his rejection by Dunya. He still keeps hope alive that they can still be together. Which includes setting up a not so elaborate scheme to frame Sonya. After inviting her to his room and offering to help out her family financially he then proceeds to slip in money into her pocket. And then during the funeral, the funeral for Sonya's father no less, he accuses her of stealing. He wants to cast Sonya in an even more negative light so that he can make it seem that Raskolnikov is wrong about her (when R said the women were all equal). Though that plan is flawed and his reasoning is confusing, because Dunya broke off the engagement after discovering what a manipulative control freak he is. But even it his plan did work she probably wouldn't go back to him. The problem was quickly solved when Lebezyatnikov tells the crowd that Luzhin slipped the note and when R explains Luzhin's reasoning. Luzhin quickly bows out of the apartment. And the landlady, who somehow believes that everything is Katerina’s fault, kicks Katerina and her children out out. Then R chases after Sonya, probably to invite her again to run away together
