Anyone who is honestly interested in the military campaign should read the daily assessments here:

They were saying that Kyiv would be impossible to capture weeks before mainstream sources were saying this. Their assessments have been spot on.
TLDR: Russia doesnt have the manpower (morale or otherwise) to continue taking territory. Although Ukraine has its own issues with ammunition/need for for more weapons and Russia's ability to counter Ukrainian drones (which they were unable to do earlier in the war, their have gotten their shit together now). The situation for Ukraine remains dire.
