Question from Candace - Anne Boleyn's actual power and responsibility in decisions

How responsible was Anne Boleyn for the break-up of Henry VIII and Katherine of Aragon's marriage and her subsequent mistreatment and that of Mary Tudor as well? Obviously, there has been a lot said and written on the subject, but I would like to hear a professional historian's perspective on the matter. In particular, what role did she play in the decision to separate Katherine and Mary, and to order Mary to wait on Elizabeth? Was there anything she could have done differently, or did she lack the power to do so?
