Where have all the pro-western Ukrainian demonstrators gone?

A couple of months ago the streets were filled protesters angry that the government was forgoing a closer association with the EU in favor of Russian ties.
Now Crimea is now a Russian province and pro-Russian separatists have seized many government buildings, hold demonstrations and demand annexation by Russia. Supposedly, they were in the minority. But evidently not. Where have all the pro-EU Ukrainians disappeared to? Why are they not in the streets? Why have they not surrounded the government buildings that have been taken over? What will it take to get them riled up again? It makes me wonder did they ever exist in the first place.
