I wish you guys were right, but I think you are being over optimistic. This war is starting to get ugly as the Russian military are starting encircle these large population centers like Kyiv and Kharkiv, and are now raining down missiles, air strikes and artillery strikes into the heart of these cities.
There are reports now that the Russian military is moving towards the Polish border, to cut off supplies coming in from the west and stop people from leaving or entering Ukraine.
Putin was probably hoping the Ukrainians would crumble quickly, but now it is a matter of pride for Putin to bring home a win no matter what the cost. I think he is prepared to lord over a hole in the ground at this point.
