I think your all being soo mean to Ron. You have to remember that hes only 14 in the movies and if you girls remember, guys were only really noticing girls were beautiful feminine sexy creature at this age so I think his attitude is really going to change about Hermoine. Hermoine is probably still a little resentful that Ron hasn't really noticed how beautiful she is and she'll hold it against him for a while but I think she really likes him even though she has a definite thing for Krum.
But anyways its very obviouse Hermoine has the same feelings because in POA when their near buckbeak and she grabs Rons hand they both kinda look at each other like ummmm.... and when their looking at the shrieking shack and says "Do you want to move a bit closer?" Ron takes it the wrong way and hermoine seems like shes thinking oops shouldn't have said it that way.
