It surely sounds like you need to find others to share your interests, and there is nothing wrong with that. Check out meetups in your area to find others with like-interests, share the few things you can with your husband, let him develop his own 'interests';
(have you asked him how he feels?)
and if there isn't enough 'shared' time as you need....reconsider the marriage.
The only behavior, sadly, you can change is your own. I still hope for others at times....or think I can be the changer---but I know better. Sometimes this can free the other person up enough for them to explore the world....it can work out in time.
Or not.
Cook for your pleasure, invite someone over who loves a good meal, make soap, candles, anything you want for yourself, and as gifts.
Enjoy the process. Your enjoyment will be attractive......and you will meet others that you can share experiences and knowledge with---can't get it all from
one person.
