Is she willing to try marriage counseling? Maybe there is a middle ground that you would both be willing to accept, you can't expect her to just suddenly shift to our cultural norms, nor should she expect you to just accept her cultural norms.

If you are set on divorce, bridging the language gap is really her issue not yours. It's admirable that you are worried about it so much, but divorce often is about self protection, I know that sounds a bit harsh, but you can't be the "nice guy" in a divorce or you run the real risk of being taken advantage of. You can always go above and beyond the divorce decree, if you want to be nice, but having it be your choice is always better than having a divorce order that you regret signing.
