Well, I would guess they have pretty much the same issues as desis married with desis have these days. Lack of communication, interference of in-laws, cheating, etc. Other than that I can't think of anything unique because surprisingly we are hearing of as many divorces in desis as well.
But then I don't know that many examples so someone may provide a better perspective.
I would tend to agree, but I heard about one such divorce it happened because this girl said that her life got very boring after getting married to this Pakistani guy. She missed clubs , concerts, her former male friends etc etc.
Although he was not a practicing Muslim but she was. But one fine morning she moved out and filed for divorce .
I knew this couple first hand , they were close family friends of my SIL. She said that to my SIL.
