I don't have a title for this

You are so right. This should be addressed. It matters now. If someone says they can't be with you unless you change, they should understand that's something you can't slough off because that's not going to change and it needs to be addressed right now, rather than down the road. That would just make things worse. This is an issue that must be addressed. It makes no sense to just let it go and pretend everything's going to be okay. That's not being responsible on her part. It will just hurt worse down the line when you may feel forced to break it off with her. And this is much too important of a subject to just let go

You have every right to worry about if you are passionate about it. The longer you wait the harder it will be. Sit down and have an open conversation about it and tell her it cannot wait, that you really need to talk about it. Best of luck to you!

Those last two words show that she knows it will be a problem eventually too. It's better to talk that out now before wasting years...

Honestly, if the relationship is good, I would personally wait until that moment arises, but be fully prepared when it does arise.

It is a huge incongruity. Sorry.
