Platinum,
It's not your fault, and obviously you are desirable even if you are "fat".
He is just being immature and is mad cuz he can't have his way.

You dont deserve to be treated like a piece of meat, and you owe him nothing.

He was just in it for self-gratification.

It doesnt take away from your beauty and desirability just because he's a perve.

If a guy just wants to call you when he needs phone sex or any kind of sexual stimulation, he is NOT the right one for you and isnt worth even a second thought.
