Definitely my kind of story. You need to run it through a spell-checker though. And there were a few other major problems I had with it.
First, it doesn't sit right with me that this woman gets so aroused by teasing him sexually (which is basically all that happens in the entire story), yet in nine chapters (over a month or so?) she doesn't seek to achieve a single orgasm. I mean, I understand the fantasy you were going for, but some regular, conventional sex would've been nice.
Second, it was a very poor ending -- not even an ending really. A story this long needs closure. The whole thing with his ex at the end left it open for another couple of chapters, and you didn't make it very clear as to whether or not the curse had run its course or not.
Finally, there were a lot of things happening in the background that could/should be fleshed out, what with the shifting reality and all. The wife's job (how exactly does a 19-year-old college drop-out land such a wonderful job?), same thing with his job (by the way, it's illegal for an employer to refuse employment based on physical disability), the "lab accident", and the history between Jack and Rebecca, and Ashley and Rebecca. And how does his ex-student know him if he never became a teacher? And that whole scene with the fortune-teller seemed rather pointless.
Anyway, I really enjoyed it, but I think a serious-re-edit could make it a helluva lot better.
