Does this mean anything?

Hey, so a quick question;

I've started developing feelings for my friend with benefits, so every little hint he gives me, I take it very personally.
Today, he said we are "connected like jing - jang" , and as far as I know, jing- jang symbolism is used to describe people in... love?
So why would a casual friend with benefits say that?
