The highly religious and much beloved (by the people at larger) English Queen who happens to be the Emperor's aunt conveniently falls down a flight of stairs or a fatal 'natural' incident in the midst of a dispute over whether or not she'll 'retire' to a convent after an annulment admitting she's been committing adultery for 20-odd years. Gee, why didn't H8 think of this one? Probably because he realized that it was an idea that could easily be applied to his initially very reluctant non-mistress mistress and queen-elect Lady Anne Boleyn and didn't want to give anyone of Anne's enemies or his wife's relatives/backers any ideas along that line.
Parliament just wanted an acceptable husband for Princess Mary, heiress presumptive. Only H8 was thinking with the 'little head' and couldn't see that (the little head only involved making Mary). If H8 had spent as much time trying to find a competent, strong husband for Mary (with the marriage contract tying his hands from becoming King and allowing Parliament to enforce the 'Prince Consort' not 'King Consort'), we wouldn't have had "Bloody Mary" and the RC prejudice that followed her rule.
As for the court
@ShortsBelfast references, those were the people around the King and Queen and caused as much problems for the crown as they helped it. (Wolsey, Cromwell, as well as Norfolk forever pushing a niece forward, Buckingham's ambitions, the Seymours - to name a few - were all jockeying for position to get the king's ear. H8 seemed to be easily influenced - hence his refusal to see anyone once he'd condemned him/her.)
But to answer the OP's title query: H8 doesn't marry Anne Boleyn until Katherine of Aragon dies. Possibly as OTL in 1536, possibly a little longer since if he's not breaking with Rome, he's still treating Katherine as Queen, easing her physical and mental stresses. She might not die for another year or two. Anne might not want to wait; she might well enter a convent to avoid him completely or elope with someone (possibly abroad to avoid trouble for her choice of spouse - her father's position might well allow this).
