Sorry to hear about your dilemma. Something similar happened to me, I believe the sad truth is that your husband sent you back to Turkey to get rid of you, and this is actually abandonment if you could prove he never had any intention of joining you in Turkey. You don't say where you got married and if your marriage is registered in Turkey or not. If you now live in Turkey and have no intention of returning to the States, perhaps you should file in Turkey. Note that if you file in the States, the foreign judgement would still have to be recognized in Turkey and this could only be done through the courts, ie: the judgement won't be automatic. If you'll return to the States for good, then you should file there. At any rate, you should consult a lawyer to figure out the best way to proceed and ensure you protect your rights and that of your son's.

I wish you good luck & stay strong.
