Ok, from what i can see is that Ron is making some bad decisions. Sure, i think that if i had a girl like Hermione now, and she was doing the exact same things, i would rather handle it myself. Ron is too self-centered to think things clearly, and as far as i can see the relationship between Ron/Hermione/Harry is going to end bad...
...but then again, it is your story.

It is my story, and I will just have to suprise you. But people are starting to see that Ron cares less about Hermione the person, and more about Hermione the only female currenly available to him. Or Hermione the girl he has fantasized about for 2 or 3 years.
It might end badly, or it might just end. Or they might be able to move on as mates, but I doubt it will ever be the same.
