I know of my colleagues who have left their children back in the Phillipines and married again and living here in Qatar. What I feel is, to have a bond with your children it is necessary that they grow up with you and understand and love you and you in turn love them. I feel sorry for the kids left in their native countries by their mothers. I don't think it's worth it. Children will prefer your presence to the luxuries (the list of which will never end). Childhood is a beautiful period. Later on they will be busy with their own lives. I am a working mother with 2 children one aged 15 and the other 9. I do a straight shift duty and my husband does split shift to be with the kids.But I always miss my children even when I sit in the office.
