Depends to which sources you're listening to. Reddit and EU mainstream media are filled with constant propaganda that Ukraine is holding up and Russia is suffering from sanctions and loosing the war, but if you listen to actual military experts from the likes of Mi6 and USA agencies, they are skeptical of Ukraine being able to win this and western sanctions barely changing anything in favor of the Ukraine.
I don't think you need experts to see how the Russian offensive has stalled everywhere. Even in the south they barely make any progress at all.
If you analyze the actual situation, they're stalling there for good reason, nor because they can't go further. They're setting up permanent bases there so they can resupply easier, setup a field hospital and a service center for vehicle repairs. It will make next offensive much more efective, in theory.
