Are you an ex-pat in Belgium? Good luck to your wife,
We live in Spain. My wife is a British citizen who lived with me in America for 10+ years. When I wanted to retire we chose Spain to be close to her family without the nasty British weather. We live an hour from the 3rd busiest airport in Spain so it is easy to catch low cost flights all around Europe. After relaxing in the sun and gardening traveling is our big leisure activity.
