英文翻译：等待不是为了你能回来，而是给自己找个借口不离开

My waiting is not for your returning but an excuse
for my not leaving.

Waiting is not for your coming back but it is rather an excuse not to leave.

You can not wait to come back,
But to find an excuse not to leave their

Waiting is not because that you'll come back,but is looking for an excuse for me not to leave.

一句比一句经典，真是知道了什么叫集思广益了。但我认为还能更简练一点儿：Waiting is not for you to coming back but only an excuse for me to right here.
