for first part, such things couple need to discuss between them, whatever the outsiders keep saying, have a common agreed response if hassled by others. both should be ready mentally to start a new family and kids.
It depends, If i am already well settled in Dubai i will make arrangements to have my wife with me. but if i am going on a first job, i will go alone first, see how it goes, then make it possible to bring over the wife as soon i can do that. I wouldnt try to take my wife to a new country new place and new job etc and may possibly struggle in start. looking at the posts I dont think he want to stay away from his wife all life and abandon her! she need to discuss with him calmly and make long term plans. she just got married and pressure is too much on her to mix up with new family, new responsibilities as wife and daughter in law. things she wouldn’t have care in her parents house, she need to tackle those issues acting like a responsible person. that will not come instantly to anybody.
