From what I've managed to find, they seem to be on the same wavelength, yes! There is a lot of melancholy and nostalgia in "mi-e dor de tine," it's an ardent longing to interact with that person, or to simply have their presence around again. And it's not just related to people, it's used whenever referring to someone or something which generated profound satisfaction in us, like food, activities, music, etc. And I've noticed that few people use it outside of its intended emotional context (like "awesome" became a generalised superlative for "good" when it initially meant "awe-inspiring").

As for the number of speakers, I didn't manage to find a lot of concrete or up-to-date information (although I am researching this halfway through my morning coffee, so I may have missed something), but Wikipedia (with this article from 2013 being cited as a source) states that about a quarter to a third of all Romanians spoke English a decade ago.

Anecdotally, I'd say that number has remained relatively unchanged, as while more people have been exposed to English in one way or another, we've also seen a significant uptick in emigration during the same period. Plus we've started dubbing a lot of cartoons in Romanian, which I suspect has contributed to fewer children picking it up early on.

As an addition to my initial comment, in which I focused specifically on people who have Romanian as their primary language, we also have significant portions of the population who speak Hungarian, Ukrainian and Roma as their primary languages, accounting for about 9% of the population (again, the numbers are taken from the sources listed above, so I take them with a grain of salt in terms of absolute accuracy).
