A man has been left sick to his stomach after discovering his old man has been dating his half-sister. He explained how his 64-year-old dad was dating his half-sister for months before learning about their connection - but chose to continue their relationship despite it.
Taking to Reddit, he said: "My mum had my 50-year-old sister when she was very young. She never played a role in her life and her dad moved her to another country where she lived all her life. My mum met my dad and they got married and had me - but they got divorced soon after."
He went on to explain how his dad met his half-sister by accident - and struck up a relationship with her after getting to know her on a deeper level. The man added: "He did not know at first who she was. They started dating and it was only later they found out the connection.
