“既然你已经不在了，那么请你记住我”用英语怎么说，谢谢。

这句话意思有点不清,什么叫不在了.请说清楚才好翻译,否则就是中国式英语了
Now that you have left, please remember me.

Now that you're not here any longer, please remember me.

As you have left,don't forget me.

since you've been not here physically,please keep me inside your heart mentally.

Since you already left, then please remember me
