Although really, the clumsiness of it just kinda drives home how real it is. These aren't ideal people having the ideal breakup - it's messy and human and neither perfect for either party, or over-the-top dramatic to the point of being soapish and unrealistic.
I really get the feeling from this that these are two people trying to do what's right in circumstances that just kinda suck. I love it, and I don't even read X-men comics from before the turn of the century :P
