This is simply a case of him being upset and not getting what he wanted, and trying to manipulate your feelings by demeaning you. He was hoping that tearing you down would make you want to "prove him wrong" - by giving him what he wanted.
Thankfully, you seem to be smart enough not to be manipulated that way.
