想忘记你英语什么说

I want to obliterate you from my memory
我想把你从我的记忆里删除（这句话更能表达你想忘记他的本意）

obliterate
vt.
使消失; 除去; 抹煞; 使湮没; 使被忘却

涂去; 擦去; 删去(文字等); 消灭...痕迹

我更同意ARIEL的说法，

虽然WANT TO FORGET YOU语法没错，但很少听外国人说I WANT TO GORGET YOU的，因为FORGET本身词义就含有已经过去了却忘记的了意思。很微妙，就是好像LOOK FOR 和FIND这个词的差别。

所以i want to obliterate you from my memory （他少了一个TO有小小语法错误）可以，或者i don't want you (to be) in my mind any more 都可以。

I want to forget you.

I want to root you up from my mind.
