Ahhhhhhhhh...
Crud, there's a short story by Nathaniel Hawthorne and I just can't remember what it's called...
The Birthmark!
It's a perfect story about a healthy, two directional relationship. :-)
I was in one of those once... She called me up about a year ago and told me to watch Eternal Sunshine of the Spotless Mind and it resembled our relationship. Of course I told her she could go F herself (I'm a nice guy but she could just push me over the edge and I used much harsher tapestry of words that would have blushed a sailor) and never to call me again, so far so good.
I haven't seen the movie yet and refuse to do so to for obvious reasons.
