What a tough decision you have! This is my option you never get over the guilt about taking your kids away from family, this really didn't help me settle for a while & I hated oz for a good 2 / 3 years . If you sell the business & the new owner didn't keep your family on your time in oz will not be an enjoyable one!! You would feel so guilty about what you did. Moving here is the biggest & hardest things you will ever do. If I could turn the clock back I wouldn't have come my kids really miss their grandparents & the guilt gets harder even after early 6 years don't get me wrong I enjoy living Here for now but I know it's not forever so I don't envy your decision xxxx
