如果直译，感觉会很odd哦。 在同样的情景下，为了表达我舍不得你走，可以说"i don't want you to go."或"i'm gonna miss you soooo much."也可以翻成I can't bear the thought that you are not gonna be around，但是这比较适合用在写诗写文章抒发心情，不太适合用语口语。 “我舍不得花掉100块钱”的表达就要看看具体语境了，如果是手头比较紧，可以说"i'm a bit short (of cash) lately,i'm gonna save that money for something else."如果是因为觉得要买的东西有点贵，可以说"i don't wanna/am not gonna spend 100 on that."

"我舍不得你走" can be (similar to what Bonnie said): "I can't bear the thought of you leaving," or "I can't bear the thought of you gone." "我舍不得花掉100块钱" is closer to: "I'm reluctant to spend that $100," or, if it's spending on something specific: "I'm reluctant to spend $100 on that."
