Otherwise, being able to appreciate and enjoy the passion of your partner
seems like a reasonable situation/hope/expectation/goal, something that can
definitely enhance the relationship.


I agree. I'd say my wife appreciates, but does not share, my passion for
stargazing. I'll show her things now and then and she's interested and
always takes time to look. But then she usually goes back inside. This is
fine. I've always stargazed alone and rather like it that way. My wife also
doesn't mind that i spend a few nights a month out on the desert someplace
with my scopes. We also go on camping trips together and after i tuck her
into the tent i'll stay up another couple hours under the stars. Is good.
