My situation isn't the same as yours (we left the Church but I'm returning soon and he more than likely won't) but here's the way I look at it.......and I hope no one takes offense to my simple analogy.
It's like anything else in marriage...like us.....my husband likes to watch football, I don't. If he watches football in the house, I stick around the house and do my own thing, perhaps surf this site next to him on the couch while he watches football. Should he ever buy a ticket to a football game and want to go, that's fine with me....I just won't go because it's not my thing....he's got buddies and our son to take along and enjoy the game with him....
My thing is scrap-booking....his, of course, is not.... if I want to have a friend or two over to scrapbook it's fine, he hangs out and keeps himself occupied and secretly listens to the chatter that ensues .....and if I go someplace else for a crop, I certainly don't expect him to go LOL
Yes, I have a point, and I'll get there
I know there aren't any "eternal consequences" to both of us having these separate "hobbies"...however, we support each other in what the other one likes. I every once in a while, I'll buy him something sports related, and he may go online and buy me some kind of crafty thing as a surprise and take a little more interest. The point is that we meet each other where we're at and one would never expect the other to give up what they like.
Perhaps I'll go to a football game one day with him, and in turn he'll help me scrapbook the tickets and the pictures I'd be bound to take of the occasion
You both go and do your own things for now, and perhaps you will find some common ground later on down the road. If you push the issue, THAT is what will cause the problems, NOT the religion you choose. Trust me, I KNOW
I wish you the best :)
