YOU SAID:
You're not married, you don't even have a girlfriend
INTO JAPANESE
あなたは結婚していない、彼女もいない
BACK INTO ENGLISH
you are not married and neither is she
INTO JAPANESE
あなたは結婚していません、そして彼女も結婚していません
BACK INTO ENGLISH
you are not married and neither is she
That didn't even make that much sense in English.
