We say that they are toing and froing.

我们说他们在来来回回。

Come on, we've been toing and froing on this all week let's just make a call.

来吧，我们这整周都在纠结，让我们直接打电话吧。

But unlike toing and froing where you're switching between different opinions or different ideas well this expression is more about actions and decisions so when you keep changing the plan.

但是和反反复复不同，意思是你正在不同的想法之间切换，这更多地是关于行动和决定，因此就是当你一直在改变计划的时候。

It wasn't just the time, although the endless hours spent at hospital, the time spent toing and froing in the car, the meetings – oh God, the meetings – took up so much of it.

不仅仅是时间， 尽管在医院度过的无休止的时间，在车里来回走动的时间， 会议——哦天哪， 会议——占据了很多时间。
