I once dated a woman who was always going about how she was still in love with her ex, even though he'd ran off with another woman.
My patience finally ran out when she told me she lets him visit her to mow her lawn and do odd jobs around the house, so I told her- "Listen, I don't want him coming anywhere near you, he's history so forget him!"
"But i still love him" she said, so I ditched her..
