If you marry for good reason, to seek a happiness in this world and hereafter, I think you already have the good base. Next thing is to maintain your love, understanding, respect and appreciation toward your husband.

The BIG gap of the cultureS would be the biggest challenge compared to other couple with the same nationality.

Back to basic again: love, understanding, respect and appreciation !! If you both have these aspects, Insyaallah everything is gonna be okay ..

I am the living proof :) been married to my pakistani husband for almost 8 years now and blessed 2 wonderful boys ...

May Allah bless you ..
