is horen not a dative verb?
The verb is hören, not horen. (Or if you can't spell that: hoeren.)
And no, it's not a dative verb. It's a normal transitive verb that uses the accusative case for its direct object.
If you combine it with a prefix preposition like 'zu-' (as in zuhören / zuhoeren) then it becomes dative and means listen to
This should also be the same as " he would hear me" when the question is reversed, however, it is not so WIRD and WERDE are very different, although the meaning is similar.
