jadzia's death in DS9

i've been watching the DS9 series late and i realize that's half the reason i've missed news like this, but if anyone can remember back i would appreciate it.

even if i didn't think Jadzia Dax is the ideal woman, her death at the end of the 6th season of Star Trek DS9 doesn't fit. There was so much for her to do, her marriage with Worf, her connection to all the other characters, it just doesn't fit. I'm convinced the reason she was killed wasn't the writer's idea. Does she have a lover in real life that didn't approve of her role in DS9? Did she lose interest? financial trouble? i would really like to know.

I will check this message board for the next week or two, but if i don't get a response within that much time and you have an answer, email me at [email protected] (i keep changing ISP's and my real yahoo id just failed....maybe i'll get another real one someday). I appreciate anything you can tell me.
