Why Pakistani dude and white girls/women end up in divorce ?

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.
