They are now in what we call an exploitation phase, where they're kind of running riot until the Russians can stop them from doing that. Russian resistance will naturally increase and Ukrainian friction will increase because of logistics, because people are tired, because of the distance that supply lines are stretched and so on. There will be a natural point where the Ukrainian offensive will culminate. It could be days, could be weeks. But when they do, they'll have to consolidate.
After that, there are three real options. Do they stand fast where they are at the end of that exploitation phase? That's a fairly large bit of ground and a fairly long line to defend. Do they withdraw back into more defensible terrain that might actually straighten the line that the Ukrainians have to defend instead of just the frontier? Or do they withdraw entirely, which would also be a sensible thing if you want to preserve all your forces that were involved and then use them for other opportunities to go back into Russia, and other locations.
