The answer was yes.
Truth be told, if I hadn't expected the answer to be a reassuring "no," I don't think I would have asked the question.
Shavuot. Sukkot. Shemini Atzeret. Simchat Torah. All of those holidays that I never observed, even when I did still believe. Heck, with the single exception of Sukkot, I couldn't even tell you what those holidays are. But from Shavuot to not one, not two, but four (out of eight) days of Passover, the expectation is that I would observe these holidays.
In his defense, he then clarified that I would not be required to observe so much as that it would be meaningful to him to observe with me. It's important to him to observe with family, with the people that he loves, and I get that. But it also worries me.
I don't believe in God. My days of superstitiously replacing the "o" with a dash (you Yids know what I mean) came and went with adolescence. I believe that nearly all religion (with the single exception of religions of personal growth, like Buddhism) serves two purposes: to scare kids into obeying their parents, and to scare adults out of having sex indiscriminately.
I remember distinctly talking about "myths" in first and second grade, and our teacher telling us about the silly polytheistic religions people "used" to believe in (nevermind that at least two of my peers in that school were most likely Hindu). Judaism and Christianity were "religions"; everything else was "mythology." It took me decades to really understand that it's all mythology -- that what my parents taught me is just as bullshit as what Catholic children are taught, or what Muslim children are taught, etc., etc., ad infinitum.
I will gladly concede that there's every chance that I may be wrong. I don't know -- and that's kind of the point. To me, anarqueso got it right when she commented "For me, being Jewish isn't a set of behaviors or rituals. It's just being part of a long story, most of which is unknown to me." There are a handful of observances and rituals that make me feel connected to this "long story," but, other than that, most observances feel foreign and arbitrary. It's like when you go to the wedding of somebody whose religion you don't share, and then there's a religious part of the ceremony, and the folks who are that religion all know exactly what to do, and you're standing there thinking "um ... OK ... what just happened?"
I very much want to be with this man, but I very much don't want to be a part of organized religion, and I'm not quite sure what to do about any of this.
