ohhh joy the topic again of an "imported wife." Sorry I know too many people whose lives have been destroyed because they married someone from pakistan, came here, and that "imported" person showed their true colors.
My advice- please think about it, right now your probably writing in the heat of the moment and give it some time. There are two children here that will be impacted. Think and pray, and let that be your guide, if after a week or month or whatever you think is a legimate time things don't improve then you have every right to do what your doing. Also, on another note, if i were you i'd take the whole she's not talk to me bit and ignore it. If she doesn't want to communicate (which i have observed many imported pakistani wives do the silent treatment, I feel like most people born in us, uk talk things out), then fine don't communicate, just go about your ways, if she doesn't cook- offer to take the kids out to dinner. at the end of the day they are your children and dispite what happened between you and your wife, they shouldn't suffer.
from, firmly against marrying against pakistan,
