SecondHalf,
Thanks for your reply. I do like your rational. I did the smart thing by pausing without sending, and taking my concern to a safer forum.
Back story: We met back in October for a lunch date. Then there was nothing for a month until she messaged me and said she met someone the same day we met, but it didn't work out, and that she'd understand if I never wanted to see her again, but she would love to get together if I was open to it. I waited a few days, posted here for some advice, and ended up telling her that I'd been busy and we should see how things are in a few weeks. I sent her a message just after new years, and we met up a few days later. We ended up seeing each other six days out of twelve, twice just for a shared meal and then I ended up staying at her place two nights last weekend. She was out of town for three days as well. While we had a hell of a lot of fun, we did not go all the way (but have gone everywhere else). I'm not just out for all the tail I can get.
As for your questions:
1) If there is no or little feedback from my letter, I'm fine with that. Towards the end of the letter I told her that I expected no response, and that I was writing for myself, ultimately, but I wanted to give her a chance to know me better too.
2) If I feel vulnerable? I think that's a bit of the point, actually. In deciding to try to get closer with someone, if you don't let yourself feel vulnerable, you likely aren't going to get anywhere.
3) Does she need such a letter? Probably not. Not sure this matters, but I'm a rather serious Scorpio, and she's a freewheelin' Sagittarius. If we go by the Zodiac, we've got challenges. If we don't, we've still got them. But I do know we have some of the big stuff in alignment (and I'm not talking about the stars here) and we've both expressed some interest in doing things differently and writing our own rules.
Finally, if this falls apart, I'm not worried. I've been seeing another woman for about two months and we have a good thing going too. She's a flight attendant so not in town all the time. I've got options, and the letter was in no way intended to force a decision on anyone. I am finding it interesting that the flight attendant is not driving me to any such letter writing, but she's totally in to me and will literally bend over backwards to please me. I suppose that situation is lacking the thrill of the chase. I've also had a few rather tame dates with an Opera singer/teacher who is quite attractive and while we haven't seen each other since early December, the lines of communication are still open...she has pursued me after I backed off to focus more on work (and the flight attendant, of course) So life is pretty good.
