I don't want to stir the pot, but as a comment below links, Pretty responded with a statement[0]. He doesn't say this is what happened at all but that's a conclusion one can draw if you just read his statement. He doesn't insinuate it directly but he says they were consensual relationships and the two people are upset about how they ended.
