我已经喜欢丄你的英语怎么说

明明是中国人干吗学外国佬

我已经喜欢丄你

I have taken a fancy to you!

I have taken a shine tou you!

I like you...

逗可以

i'm in love with you.

i've fell in love with you.

i like you.

上面都是最普通的表达。
下面是外国人常说的，比较特别：

i'm fond of you.

i fell for you.

i have a crush on you.

i have a fancy for you.

来点不一般的，呵呵

我被你迷住了：
I was enchanted by you.
I was charmed by you.
I was magnetically drawn to you.
You has me hypnotized.

I've started to like you.

是喜欢，不是爱，所以不能说fall in love或者fall for you。

or:
I've started to have feelings for you.

I have fallen in love with you!
