中译英：还是介意你的过去。

I still couldn't forget your past.

I still couldn't put your past our of my mind.

(I am afraid) I still couldn't put your past out of my mind.

我觉得就说成：我还是无法忘记你的过去，这样已经够明白的了。
或者说成：我还是无法将你的过去从我脑海中抛去。
这样同样表达了介意的意思了。

I still mind your past time

I'm sorry I have to tell you I still mind your past.
