Prince Harry may be head over heels for his girlfriend Cressida Bonas, but some of his friends and family don't think she's the right choice for the royal.

A source revealed to E! News that some in Prince Harry's close circle of friends don't think he should get engaged or get married to his girlfriend Cressida Bonas.

"There is a growing feeling among a small section of them that Cressida isn't the perfect choice for him," the source told E! News. "I don't think it's because there is anything wrong with the relationship or they don't like her, but there is concern that she is too much of a free spirit to be happy in the royal family long-term. They worry that she wouldn't be able to fully adapt to that lifestyle. They think she's too carefree and would find it difficult to live by the protocol that comes with the job, which of course it is. It might be too much of a constraint for her. And that could cause problems for everyone."

Meanwhile, Cressida Bonas may be hiding from the media to deter engagement and wedding rumors. She has not been seen in public with Prince Harry for quite some time.

"People talk to her all the time about Harry and she gets quite cross and says 'I don't want to get married yet,'" a friend of Cressida Bonas' previously told the Daily Telegraph.

"She hasn't been invited to meet the Queen yet, so she's not at the stage of an engagement being imminent."

Prince Harry will be 30 this September, a typical age for members of the Royal family to marry, The Daily Telegraph reports.

"If it was up to Harry he would get married straight away but he is very sensitive about her on this particular issue," said a source. "Harry has told her he will wait."

Harry and his girlfriend Cressida Bonas have been dating for almost two years.

"Up until now, Cressida has loved the fact they can have a lot of freedom in public," a royal insider told E! News recently. "But they are fully aware once they decide to proceed to marriage things will get a little crazy and the attention on them will increase."
