Kate Middleton does not want Prince Harry and his former girlfriend Cressida Bonas to date again even as reports suggesting the former couple's reunion make the rounds. Harry and Bonas started dating in 2012 and broke up in early 2014. 

"Kate doesn’t like Cressida at all," a source told OK! Magazine, adding: "It’s not just that she thinks Cressida isn’t a love match for Harry. It goes deeper than that. She doesn’t want her in the family."

According to OK! magazine, one of the reasons for Middleton’s dislike was the alleged fling between her husband Prince William and Bonas’ half-sister Isabella Anstruther-Gough-Calthorpe. The dating rumors began after the royal couple broke up in 2007, before their marriage in 2011.

The source said, according to OK! magazine, that Middleton is "afraid that William sees Isabella as the one who got away," adding: "Kate hates even hearing Isabella’s name mentioned."

"She was obviously upset when Cressida and Harry started dating," the source added. Middleton is also reportedly worried that Bonas may hurt Harry once again as reports alleged Bonas initiated the break-up.

"Kate’s even told William to warn Harry against her," the source said, adding: "She does not trust Cressida."

Harry is also reportedly in touch with Chelsy Davis, another on-again-off-again former girlfriend. Davis and Harry are said to have been in a relationship between 2004 and 2011.
