I'm a Russian living in the west, bilingual, and have a husband who doesn't speak it. Something people don't really talk about much is the difficulty of belonging to one culture and living in another. Your future wife doesn't just want you to learn works and recite them - she wants to be able to both speak to your future children, she wants to share her heritage and culture (which is extremely different to the US), she wants you to understand jokes from that culture and why she finds them funny, she wants you to know untranslatable words like toska and what they really mean. In short, this is about way more than a language to her.

My husband knows about 20 words in Russian. He plans to learn, but the difference is that he's really interested in Russian history and culture - he asks my parents about it, reads about it sometimes and tells me what he's found, and has his own favourite Russian dishes. The language isn't that big a deal for me, but it might be when we're closer to having kids.

As for you... I see no reason at all why you need to do 30 mins every single day and you can easily do an hour or so a week and make slightly slower progress. But from your answers here it sounds a lot like you simply don't want to do that at all. I guess another compromise is going to Russian cookery lessons so you can make some pelmeni for her every so often, or maybe learning more about Russian culture without the language. If you don't want to even do that, you're really rejecting a huge aspect of who she is.

I also have to ask, do her parents speak English? Does your refusal to learn mean you'll never communicate properly with her family?
