这得怪你，用英语怎么说？it is your fault? you must be responsible for it?

对，it is your fault可以。除此之外，还有几个句子也有同样的意思（当然，用这三个是在你认为it is your fault太简单的情况下。）
The fault lied with you.
You are very much to blame. 【句型为be to blame】
It is big blame to you that...【这个后面接着写为什么都是怪这个人的原因】——————————————————————————————————————————
P.S【此为额外知识，可以选择忽略】：另外，如果你想说：“你只能怪你自己”的话：Only have yourself to blame.
例句：If you lose your job, you will only have yourself to blame.
如果你丢掉了工作，你只能怪你自己。希望以上答案可以帮到您。
