Molly Flynn

Molly Flynn-Biggs (Melissa McCarthy) is the lead female protagonist of Mike & Molly. She is a fourth grade school teacher who attends the same Overeaters Anonymous class as Mike. She lives with her mother Joyce and her sister Victoria, while her mother's partner Vince Moranto is often seen at the house. She is very sweet, intelligent and caring, but she can be hypersensitive and has a very bad financial history thanks to a large amount of credit card debt. She and Mike married in the season 2 finale. She and Mike spent two years trying to have a child but put those plans on hold in Season 5. In Season 4, she quits her teaching job to pursue a career as a writer, and in Season 5 she has a huge success when her literary erotica novel is published by a major company. It is later revealed in a session with a psychologist that Mike's stabilizing presence, something she hasn't had since her father died, has allowed Molly to finally feel comfortable taking risks.

Melissa McCarthy won the Primetime Emmy Award for Outstanding Lead Actress in a Comedy Series in 2011 for her portrayal of Molly Flynn.
