They were expected to marry this August.
In a statement Rory says:
'There is no right way to end a relationship that has been so important to two people. The problem is mine. The wedding invitations issued at the weekend made me realise that I wasn't ready for all that marriage entails. I wish Caroline all the happiness she deserves and thank her for the great times we've had. I will not be saying anything more about our relationship in any setting.'
Just 3 days ago they were celebrating together in Monaco:
