"...piece in the backseat."

I was talking to this guy online for a few months. He always listened to what I had to say and let me vent, and he always responded when I messaged him. I told him about my love life and about school, and I sent him pictures of myself (nothing graphic).

Then one day we got into an argument, and he completely turned on me. He used everything I had shared with him against me. He twisted my own words around and used them to hurt me. He said: 

"You think because you are overweight you are worthless, so you will sleep with anything, male or female, and think it's cool. But no one will ever bring you home to meet mom and dad. You will always just be some piece in the backseat."

This was four or five years ago, but I still remember word for word what he said. I memorized it.
