My wife dives, but only likes warm reefs from a boat...she's willing to do it, but it's not interesting enough for her to put any real effort into it. Which is fine by me, as long as she doesn't attempt to control my diving any more than I control how often she goes shopping. I find those sorts of control games in a relationship a deal-breaker, and would react especially strongly to being on the receiving end of them from someone who has their own significant hobby.
Do whatever you think will work for you, but I wouldn't put up with the crap you've described, even from my spouse. If they can't act like an adult, they're a waste of one's ever decreasing time left above ground.
