YOU SAID:
I am in love with a guy who dosent even know I exist
INTO JAPANESE
私は、私が存在することを知っていても
BACK INTO ENGLISH
Even though I know that I exist
INTO JAPANESE
私が存在することは分かっているが
BACK INTO ENGLISH
I know that I exist
INTO JAPANESE
私は存在することを知っている
BACK INTO ENGLISH
I know that I exist
That didn't even make that much sense in English.
