Putin has left the Ukrainians with no choice but to continue fighting. A ceasefire would give all that wealthy/productive territory to Russia, making them that much stronger when they inevitably return to Ukraine in a few years and finish the job.
Literally thousands of Ukrainians have stopped fighting and surrendered because Russia continues to give them the choice to do so.
If anyone is forcing Ukraine to continue its the Zelenski regime in Kiev.
Nothing is going to change that. And, the people in Kherson and the areas the Russians are in are fine with being under Russian control. Those areas a filled with ethnic Russians that have been persecuted and targeted for eight years.
The only question that remains is whether or not Ukraine will surrender and save Odessa and some access to the Black Sea. If it doesn't, then Ukraine will be rump state and landlocked country, completely dependent on US and Europe handouts.
