Londoner Jackie Mitchell recently attacked her boyfriend after she found out he was sleeping with her mother. The 24 year-old says, "Whenever I was with my mum and phoning David, she would ask to speak to him and they would chat and flirt. Then a relative told me my mum and David had been seeing and texting each other, but he denied it. My worst fear is that David was sleeping with me and her at the same time."
