My partner lives and works in mainland Europe, I'm in London - I can get to him in 2 hours on the Eurostar. Before lockdown I would do so 2 x a month, and he'd come here 1 x a month.
I last saw him in early March and miss him terribly. I've been following the guidelines to the letter, and so with the introduction of support bubbles and European mainland borders re-opening next week, WIBU to travel to see him? I'd wear full mask, gloves etc and am happy to quarantine myself on return.
