I am baffled as to the reason why Jo Rowling did not explore H/Hr as a
ship?

Lynda answered:

H/Hr is not what JKR wanted for her story.

  Comment:  If you are looking for evidence that JKR didn't want H/Hr for her story, I suggest that you don't seek it within the first five books of canon.  It isn't there, in my opinion...in fact, I'd say she was exploring H/Hr up through OoTP (particularly in Book 5)...which is partly why I was so disappointed with HBP and it's forced rehabilitation/re-packaging of Ginny as a suitable match for Harry.  Of course, there's JKR's interviews to fall back upon, but it's one thing to say H/Hr is "delusional," and quite another to convincingly show my opinions to be "delusional" within the sustained narrative.
