I disagree. In most relationships (certainly in any
healthy relationship), there is empathy and power sharing - two qualities that Haruhi could
really use to adapt herself to. A relationship could very well take some of the rougher edges off of Haruhi, and make her a more well-balanced and hence ultimately stable person. Sure, there's likely to be a few bad fights along the way, but the end result would
definitely be worth it, in my mind.
Also, if its Kyon... do you think that Kyon is
capable of giving Haruhi a bad fight?
Even in "the dream", his words were never particularly harsh towards her whatsoever.
Edit: In fairness to you, though, I'll say this - if Haruhi was to actually get dumped by a long-standing boyfriend,
that could be disastrous. Anybody who becomes her boyfriend for more than a month is basically going to have to stay that as long as Haruhi wants him as that... or the world's in jeopardy.
Glad you liked it.
