After a chance meeting with Aidan at the opening of a bar he co-owns, Carrie convinces him to restart their relationship. Aidan eventually moves into her apartment after purchasing it when her building goes [[co-op]] and later proposes. Despite her initial misgivings, Carrie accepts the proposal but soon realizes she is not ready for marriage. Although Aidan initially agrees to give her more time, he soon begins to pressure her into marriage, revealing his lingering mistrust due to her past affair with Big. They ultimately break up, and Aidan moves out. Carrie buys her apartment with the down payment lent to her by Charlotte, who gives Carrie her engagement ring from Trey. At the end of season 4, Carrie discovers that Big has sold his apartment and is moving to [[Napa, California]].

Charlotte and Trey, though living apart, continue to have marital relations. They eventually reconcile, and Charlotte moves back into their shared apartment. They decide to try for a baby but discover that Charlotte is reproductively challenged. After [[fertility]] treatments and considering adoption, their marriage falls apart under the strain, and they decide to divorce.

Miranda supports Steve through his battle with [[testicular cancer]] and surgery. Later, when Steve feels emasculated by the surgery, they have sex, and Miranda becomes pregnant. She initially considers an abortion, a decision that is particularly distressing to Charlotte, who is struggling with her own fertility issues. However, Miranda ultimately decides to keep the baby.

Samantha flirts with a priest, has nude photos taken, attempts a relationship with a lesbian, and sleeps with various partners, including a man who engages in baby talk, a wrestling coach, and a farmer. She then lands a major PR account with hotel magnate Richard Wright, who is resolutely single. Their relationship begins as purely sexual but gradually deepens into something more, leading them to attempt [[monogamy]]. However, Samantha eventually catches Richard cheating, leading to their breakup.
