Could you marry a Prince and live in the public eye?

She has been with him for 9 years she has already been through it all with the media she knew what she was getting into.Infact she is better off now because she will have royal protection.She looks like princess material too i just hope she doesnt end up with the same fate as princess Diana.As An Englishman i dont really understand why people around the world are so fascinated by this.Its flattering though.
