I've never been but one of my best friends is Belarusian - she left in about 2016 because, as she put it, 'it was getting too damgerous to be a normal person with opinions'. Recently she had no choice but to go back for a few weeks and we were both convinced she was going to be picked up at the border and imprisoned, but thankfully everything went fine. She said the quality of life was unbelievably better compared with when she left (not politically but in terms of infrastructure, affordability, cleanliness etc) and that she would even consider going back there to live again, now that she knows she can do so safely.
It's possible to move to a country when you don't support its government. Plenty of western expats living in China, Dubai, Saudi - personally I'd take Belarus over any of those places, even now. I live in a dictatorship too, albeit a fairly benign one as they go, and it's nothing like what people in democratic countries imagine when they hear the word. If you don't go out of your way to get involved in politics then the impact on daily life is minimal.
