What caused the split between Chelsy Davy and Prince Harry?

According to entertainment news reporters in Great Britian, Davy dumped Harry after she found text messages to another woman on his cell phone. However, the pair have been in touch with each other the past few days.

Does that mean hope remains? After all, Kate Middleton and Prince William also broke up for a period of time and then got back together.

"Chelsy was - and still is - the love of his life," said a friend of the 23-year-old Prince.
