Maybe an MVP for an European dating platform starts at the minimum of your mother language, or say, the French market? What good is having every language if your MVP marketing budget doesn't stretch enough to warm up the dating scenes of several countries? Better hit big by divide and conquer than try to hug the continent with your legs (to use a Portuguese expression.)
Europe is more like 20 different markets than it is one big market though. Internationalization only matters if you're targeting all of those markets at once.
