As for me, I'm torn on staying vs leaving. This may seem irrational (and it probably is), but this is my home. I'll be perfectly fine in any European country on a day-to-day level, but I'll never be at home (and I'll need a thicker skin since we're the nazis now). There are people and places in Russia that I love, and my life won't be complete without them. I guess I'm just old.
On the other hand, we may soon live in a Gulag. I'm already cleaning the history of some of my Telegram chats when I go outside. People are getting arrested for holding a sign with asterisks ("*** *****") or just a blank sheet of paper, and you can get a prison term for a careless repost.
On the third hand, Russia may crumble. Our resources aren't unlimited. We are under the heaviest sanctions in history, our industry is a sham, our energy exports will cease in a couple of years, we've already committed 70% of our military to the war, and this won't end even if we "win" -- we'll need to provide police / counter-guerilla presence over a country that's 30 times (times, not percent!) larger than Chechnya, for at least a decade. And we'll need to rebuild a couple of Stalingrads to boot. I can't see how this is sustainable.
TL;DR: Decisions are hard.
