我在乎你你知道吗？有英语怎么说啊

我在乎你你知道吗？
I care about you, do you know?

§ Dream Works 翻译，坚决反对机译！ §

Do you know that I care about you?
或者
I care about you, do you know?

英文的话通常第一句比较好

you probably don't know how much I care about you, do you?
以上的几位都可以，这句我用了反意疑问，来表达“你很可能不知道我有多在乎你”，希望是你要的语气

do you know that I care about you?
英国留学生翻译的没必要不相信

DO you know I care about you?or DO you know you mean everything to me?

i care about u,ya know?

这个是比较口语化的
canadian说的你更应该信...
