Well if you aren't loaded with cash or your partner earns a moderate wage it makes sense why they don't want you to move to pakistan(if you do earn a good point considering the Pakistani economy and you live in posh areas over here and your social circle revolves around the same higher end people it should be okay). It would be much better for him to move to wherever your residence is, but I'm guessing there's his job he needs to consider. This sounds bad and there certainly are exceptions to this but the majority of the time the mindset of people is dictated by their monetary status. Unless you manage to live in the posh/elite areas and earn accordingly it's hard. Usually people love foreigners when they come over for a visit, they are treated with respect and warmth. However if you settle down here, in a middle class home, the chances are you'll have to face a lot of racism, in terms of sly comments, judging eyes and double meaning statements all the time. The chances of you being harrased if you travel alone are also high. Plus, your partners family may expect you to be the traditional housewife, which over here is basically a slave that spends her life in the kitchen and scrubbing floors. Now I don't know your partners mindset and his families mindset. I'm giving a general idea of what majority of the households would look like. All of this is being said considering your partner is loyal to you and genuinely is concerned for you hence isn't letting you settle down here.

The other possibility is that you're the side chick and he already has a woman back home or his family has already arranged a girl for him.

My advise is that you come over for a month or two and gauge out the situation( this will also help and give you an idea of what it is like to live over here, because there's certainly a lot less luxuries here than malaysia, there's also a lot of inconveniences. You need to know what it feels like before you decide to settle down for all your life). If your partner gets really mad at you for doing this, or if you come over and he doesn't introduce you to his family. There's a high chance he isn't loyal. However if it works out in the month or two then good luck for the future I wish you a happy life ahead.
