用英文说分手。

I think you can get a better guy, a guy better than me.
You are not my type. I cannot see our future.
I think we should end our relationship.
I wanna a break.
Get away from me, you bitch!

自己挑吧，哈哈，含蓄程度依次递减．

一段话啊？看看这个行不行？
I am very sorry, I don't mean to hurt you. You are a so outstanding, beautiful, smart, and everyone likes you. But, you are not my type, and I also think you can get a better guy. Can we just be friends? I think this is the proper relationship between us. Again, I am so so so so sorry. God bless you.
