Frustrated by Brexit negotiations, angry at Brussels or simply afraid of the future, ordinary Britons and other Europeans are already taking life-changing decisions a year before Britain leaves the EU.

"Other people my age, they are starting settling down, they make more long-term plans with their lives," said 32-year-old Matt Davies, a British expat in Madrid.

"It's very difficult for me to plan anything beyond March 2019 because you just have no idea what is going to happen," the call center worker said.

British and EU diplomats resumed negotiations in Brussels last week and are hoping to agree next month on a post-Brexit transition period.

But the shape of future relations between Britain and the EU is far from certain and the British government is deeply divided over how to proceed.

That uncertainty is even more pressing for the three million EU nationals living in the UK, many of whom are now questioning their future there.

Brexit affects "every part of our lives", radio presenter Gosia Prochal, one of nearly a million Polish citizens living in Britain, told AFP.

The 25-year-old is based in Peterborough, a city in eastern England that has seen a sharp rise in immigration in recent years and voted 61 percent in favor of leaving the EU in the 2016 referendum.
