[This] woman, so proud, whose contempt had so often made him redden all over, had just taken as her lover a petty laborer disguised as a tutor. (1.19.49)
Julien ain't the only person in the world with pride. His lover, Madame de Rênal, can't believe that she has allowed herself to be seduced by a lowly peasant.

Quote #6
His pride offered him the illusion that he was accepting Monsieur de Rênal's offer only as a loan, and he gave the mayor a note pledging reimbursement in five years, with interest. (1.23.98)
Monsieur de Rênal offers Julien money to leave Verrières and go to seminary school. But pride prevents Julien from accepting the money as a gift. Instead, he insists on paying the mayor back as soon as he has the money to do so.
