Right

The current will stop the instant the circuit is broken (and thus the resistance shoots up far too high for current to flow given the voltage in the circuit), or when the voltage has died down to the point where the current cannot continue circulating against the wire's natural resistance anymore.

Basically all you need to know is given by the formula I = V/R, where I is current (ampears), V is voltage (volts) and R is resistance (ohms).

If the resistance becomes too high relative to the voltage, as a result of the circuit breaking lets say, the current will become very low (effectively there would be no more current).

Similarly, when the voltage starts to ebb and decrease as the battery's chemical processes die down, then using the same formula it's easy to see how the current will decrease too.
