Yes, this is true. As for why...well, Cilla passed it off as a combination of his 'being under pressure', fear of fatherhood, and his 'moodiness'. Guess it's up to the individual to decide which, if any, of these they would blame it on. Personally, I think that he wasn't into the marriage from the get-go...and I think that he had moments, perhaps many of them, where he wished he hadn't been pushed into the whole thing. Just my opinion though...some will disagree.
