Finding a job in Pakistan might be tough, but what if the roles were reversed and you were moving there to live with him? What would he do then? There isn’t a guarantee that he will find work right away here as well. Considering you haven’t really met him in person, it’s even hard for you to judge what kind of person he is based on what he’s been typing online. Please don’t forget you haven’t met him in person.
I think if that’s the decision you’ve made, stick to it.
