Everlasting Love (Henry VIII and Anne Boleyn)

What if Anne Boleyn didn't die? What if Henry found all the accusations against her were false but decided to annul their marriage because of his 'great love' for the 'sweet and innocent' Jane Seymour. But what if he annul his marriage to Anne because she simply did not give him a child. And what if Jane gave him a baby girl instead of a boy? And what if Anne was pregnant.... with HIS child? Would it change everything?
