Solo(1981)

Solo is a British comedy series following Gemma Palmer, a 30-year-old woman who reaches her breaking point after discovering her boyfriend Danny's infidelity with her friend Gloria. Fed up with years of betrayal and being taken for granted, Gemma makes a dramatic decision: she throws Danny out, cuts ties with Gloria, quits her dead-end job at an estate agency, and declares herself done with relationships. Her plan is simple—go solo and reclaim her life on her own terms. But as Gemma soon discovers, independence is messier than she anticipated, and staying true to her resolution proves far harder than walking away.
