Human relationship is a complex phenomenon. Please always remember, no matter you marry a Nepali girl or a foreign girl, relationship changes over time. Communication plays a key role in the survival of any relationship. In order to understand some other person, you need to understand yourself first. Who are you from within? What are your driving motives? What are your aspirations? What comes in your mind on daily basis? These things can tell you who you are in general but these are just relative and can change over time. Women usually look for strong commitment and some sort of financial stability on the guy side. Communication plays very important role in any kind of relationship. How well can you express yourself in English? How well does your foreign girlfriend feel the sensation when you are trying to express in English. Most of the time our subconscious mind is at work, and we don't even know our own mind. In my case, when I get a chance to talk in Nepali, there is inner joy within me. I don't know where it comes from but I do experience the joy of speaking in Nepali. This might not be the case for everybody. However, communication is a key factor. Words are very powerful. They can heal a person, they can nurture a person, they can help grow a person. Strangers are made friends by the use of language. Language is a very powerful tool. Small things matter in relationship. It all depends on you and your girlfriend how well both of you can communicate and do small things to nurture the relationship. Relationship is like a small tree. Tree requires good environment, good water, good mineral, good fertile soil etc. to grow into a healthy big tree. Similarly, relationship requires nurturing behavior in order to survive. Once again, communication plays a key role in any kind of relationship along with many other factors.
