Prince Harry's 'marriage talk" spooks his free-spirited girlfriend Cressida Bonas "Harry has been ringing Cressida regularly," one of her friends told me at the time. "He's been pleading with her to 'wait for him" until he comes back. Cressida is still very fond of her ex-boyfriend and, since Harry's been on the scene, he's been after her again. Cressida is torn. She likes Harry, but is not the sort to be bothered about his title. The former boyfriend was Harry Wentworth-Stanley, 23, whose stepfather, the Marquess of Milford Haven, is a cousin of the Queen. The pair were a couple while students at Leeds University, but he went travelling after graduation and their romance cooled. Last July, she was said to be "desperate" to rekindle their relationship. In January, the Prince gave a bad-tempered television interview from Camp Bastion in which he complained about his difficulties in finding love. He said potential princesses were put off by his position, rather than attracted by it. "You ain't ever going to find someone who's going to jump into the position that it would hold," he said. Simple as that. If you find the right person, and everything feels right, then it takes time ... especially for myself and my brother. Harry is understood to have been influenced deeply by the happy marriage of the Duke of Cambridge, 30. His best friend, Thomas van Straubenzee, 30, is to marry Lady Melissa Percy, the Duke of Northumberland's daughter, later this year. Cressida began her flirtation with Harry before he went to Afghanistan. Her half-sister, Isabella Calthorpe, once spurned Prince William's affections. Last month, she married Sam Branson, the son of the Virgin tycoon Sir Richard Branson.
