You move here to Dxb with your family.
After a while your relationship starts to disintegrate, You move out. After a while your ex moves a new person in, without your knowledge, with your kids.
This "unknown" person doesn't have the good manners or the bottle to approach you to put your mind at rest. You know, "Look mate, your kids will be ok with me etc". Just moves in.
After a while you find out that your ex and new guy have skipped town. Leaving your kids strewn across the city......WITHOUT YOUR KNOWLEDGE!
This sort of stuff carries on for a couple of more years.
What would you do?
