The controlling political parties in rest of EU have huge interest of making Brexit costly to Britain even if it hurts their own country. If Brexit is successful and Britain improves then Euro-optimistic parties suffer future elections. Britain is having to negotiate with lots of countries interests, each controlled by political parties with their own agendas and trying to win against other parties in their next elections. Getting rid of eastern European immigration was main reason of Brexit now Britain has to get approval of countries whose population they just slandered in elections.

Its unlikely to have ANY deal between EU and Britain, there are too many conflicting interests. So the end result is that all the EU deals just end and there is no replacement deal for them. Problem is when lots of countries want to leave their own mark on the deal and lot of people in the deal making process has vested interest in making bad deal for britain and Britain really cannot approve such deals.
