The people making jokes here about suicide should be ashamed of themselves. It's no joking matter at all when people start thinking like this.
Also, it is highly possible that she has to use a proxy server to access certain sites from Pakistan which could show her ip address as Canada.
I say, give her the benefit of the doubt.
As for how to solve her problem, I am not sure. Maybe try try to get the message to his family somehow? I'm not sure if this will help you, but the man does not deserve and respect if he has treated you so badly. Perhaps you could ask them for atleast financial support?
It must be tough in Pakistan being a young single mother, but no matter how you feel now, you will have happy times again in the future, and suicide is NEVER the answer. It ruins the lives of all who are close to you aswell.
Be strong and try to stay positive!
