I dont think you would come to sajha for similar post; had she been a nepali girl. Now i have a question for you - what made you seek for a consultation in this case? Are you in dobut in your relation with her just being a non-nepali?

Listen to your instict. If it is an unconditional marriage - it works. Never judge or define a relationship based on what somebody advice. Don't let someobody else define the fate of your relationship.  It is truely personal and only you know it better than anyone else.

And yeah - marriage is a compromise.. never expect 100% perfect. Else, you will suffer.

best of luck.
