What is the main conflict in A Taste of Honey by Shelagh Delaney?

Jo has essentially been abandoned by her mother. This has been a life-long pattern, but it becomes overwhelming when Helen moves her daughter to a new flat just before Christmas and then leaves almost immediately with her boyfriend. Jo's loneliness directly leads to her pregnancy. When her mother, Helen, leaves with Peter, Jo dissolves into tears. The young black man, who professes to love her, appears, and Jo invites him to stay with her for the Christmas holidays. In the previous scene, Jo is resistant to any intimacy with this young man, who is leaving for a six-month tour at sea with the navy. But when he appears later at her flat, Jo is so overwhelmed with loneliness that she throws away her future plans for work, right along with her inhibitions.
