What do you mean by escaped the EU?
A territory (Greenland) left the EU after a single referendum and a number of other countries have ratified decisions against further integration on a single referendum such as Sweden and Denmarks' decision not to use the Euro. The overwhelming majority of referendums have been in favour of proposals or have ratified Treaties. The Danes held two votes on the Maastricht Treaty and the Irish two votes on the Treaties of Nice and Lisbon.
So the UK is the only country that has sought to escape the EU. Whether there is a second referendum is still a point of debate.
