我们完了英文

这样的说是比较委婉的说法，比we were over更让人能接受一点。这样的话最好还是不要说，特别是男生对女生说，更不好。当然这仅仅是个人建议！

WE ARE OVER!

We will be dead.

We have done. We have finished it.

we are through

we are over是我们玩了用it's over 好点希望能帮到你，如有疑问，可继续追问

We are over.或者 That's our end.希望采纳

we are over!

可以这么说。也可以说：We broke up。两者都可以，都讲得多，你多看一些美剧就会发现两者都在口语中会用到的。
