我不知道你想要表达的是不是男女朋友分手了，如果是得话，可以参照下面说法：
1 break up 分手
如果说 我们去年分手了 应该用过去时
We broke up last year
2 part
We parted last year 我们去年分手了
这两个都可以
part既有分手也有分开的意思！这在句意中可以分辨出来！
分手:
1. part
The children were parted from their father.
孩子们和父亲分开了.
1. 我希望我们和和气气地分手。
I hope we can part as friends.
2. 我们在公共汽车站分手了.
We parted company at the bus-stop.
3. 由于在另一个城市里谋得了一份较好的职位，他被迫也女友分手了。
He was forced to part company with his girl friend, when he was offered another higher position in another city.
4. 分手时，她既没有哭，也没有大吵大闹。
She didn't weep at the parting or make any time over it
