Re: Killer situation
They need attention badly? What are they, toddlers? I’m sorry. I know many people will disagree with me on this and think I’m a bad person. But your parents are not babies who need to attention all the time. You just said yourself that your parents are busy in their activities and that they travel on their own. 
They don’t sound ill. Obviously you’d know it better than any of us and I can only judge by whatever you’ve told us.
If you can’t live with your wife and you feel like this marriage is not going to work then just ask for a divorce. But forcing her to move to Pak isn’t gonna fix anything.
