One of the reasons the couple decided to call time on their relationship was thought to be so that Cressida, who is just 25, could concentrate on her career.
She completed a one year contemporary dance course at the Trinity Laban Conservatoire in Greenwich, London, last year.
The pair, who headed off on a skiing trip together to Kazakhstan in March, are said to have been introduced by the Prince's cousin and Cressida's friend Princess Eugenie - although they have moved in the same upper class circles for a number of years.
They began dating around May 2012 - reportedly getting together at The Valley festival on friend Arthur Landon's Hampshire estate.
