It is not very clear why would a person risk loosing his job by marrying you, this may only happen if you have a terrorist or a criminal record!
On a serious note, the Egyptian gentleman can apply for a tourist/ visitor visa to Pakistan, get married to you and apply for your spouse visa to live in Saudi Arabia as his dependent.
Let us hear more about how you two met?
Have you read couple of hundred posts women from all over the world have posted on how they have experienced Egyptian husbands on " Egypt" forum? You do not need to believe all their stories are true
