@SameBoat - you know what...I'd put that stuff into storage if it's worth it and email your father and take the next flight out of there and never look back. Once you are on the ground and safe I'd call the mother of this young boy and describe the home environment that you left him behind in.
I do not think you should try to remove the child physically before you leave:-
1) You are not the legal guardian/parent and you may face some sort of legal sanction for taking him;
a) against his will (even though he is still a child) regardless of your fears for this child's safety and,
b) The mother needs to be aware of any potential for push-back by the child bc he may be as hopelessly wound up in the emotional push/pull of an abusive parent as you are as a partner and,
c) If this woman harbours any anger/resentment against you for any reason and your sole aim is the child's safety she needs to know you have left this abusive man so she can say to a lawyer/court/whomever it is no longer acceptable that he have sole care of this young boy. She has to figure this out. It might well be that you are the only reason she is allowing him to stay in the house with his father. Idk.
Also if the young boy see's that you have gone and all the comfort's you provide are no longer available he might be much faster in exiting the house and relationship with his father than if you remained.
Ultimately you are powerless over the child's involvement with his father bc you have no legal rights regarding the child? Idk. Morally, you can tell his mother and anyone else that has some authority over this child what is actually going on in this home and that you have left.
That course of action blows the abuse situation open wide and you will be safely away from the abuser in the Middle East. And he will not follow you there - would he?
I would be calling my father and moving quickly and quietly. What do you think?:hug::)
