I thought the same thing, if the reports are true, that Chelsey and Harry have been fighting, then crying all night would be in order for the "neglected," "broken-hearted," soon-to-be humiliated girlfiend of a prince.
What if the relationship between Harry and Chelsey flops, falls flat on its face? Chelsey will look foolish for making it more than it was, shown by moving all the way to London from Africa just to date a fellow who was not all that serious. Yikes! This could turn out to be a very, very painful lesson for Chelsey. I hope not, but I'm afraid what she did is very risky and hasty.
I do not know, but if they do break up I do not see Chelsy as the "humiliated girlfriend" and also do not think the move overseas should be such a big deal. As Charlotte pointed out, Chelsy did her schooling in the UK and therefor is very familiar with the country and she has her own friends there. Yes, she could have furthered her studies here in SA where the weather is superb, she is closer to her family and she is not that hounded by the paps, but they (and here I'm sure they both decided for her to go over to the UK) probably decided to see if their relationship could go to the next level. She doesn't have that much to loose if they do break up. A bit OT but take Mary's situation - she left everything to go to a new country where the only person she knew was her then boyfriend. Also if their relationship did not progress she would have to move back to Australia and back to her lower middel class lifestyle. She would have gotten accustomed to luxury and then all of a sudden back to not being able to afford paying of a credit card. But with Chelsy, she is still young, she is ambitious (she is not studying for a Mickey Mouse degree) and she has the wealth of her family to fall back on. Personally I think she would loose way more if she stayed with Harry.
