I think Splunge is saying that the agent got married and wasn't able to adequately pitch the revised novel or wasn't able to help revise the novel in a way that the publisher would accept it or find another publisher who would be able to publish it due to the whole business of "getting married."
I used to keep all my rejection letters, then after getting no acceptance letters I gave up on the idea of unsolicited work and moved into just doing what I wanted for no pay or providing what was asked for with pay. I had some good ones. I had some really mean ones too.
I once had the same story rejected by the same editor twice. She read it while working at a magazine that was going out of business, then sent me an email saying she was doing an anthology on her own once the magazine folded and I should submit it to her there is a few months (after I made the changes she requested). So I did and she rejected it again, but I don't think she realized it was a resubmission since she acted like she'd never read it before.
Actually, TrishaLynn has it sort of. My agent was a good friend of Paul and his wife. Paul's wife was going through some serious health problems, even when we met. This being so, shortly after our meeting he had to take a leave of absence.
Time goes by. And Shari also decides that she will do her own personal things. And I lose touch with Shari after a phone call that tells me that she has met someone. I never hear from either Paul or Shari. The one time that I tried to get in touch with Paul, the answer is that he no longer works here.
And so. I hope that the persons above are healthy and safe. And honestly it didn't ruin my writing career or some such. I just never looked for another agent. I'm a lazy guy. And writing is a tough job.
As far as I'm concerned, that letter is the best thing I'll ever get.
Oooh! OOh! Except that Shari, who was a Grad Student. Gave my stuff to a Prof named King. Dr. King loved how I wrote. And now I miss him too. Dr. King was so very cool.
