to attack your ex husband , not the right idea to say about fake documents ,
what u gonna win later , even if there s a chance to support u and your son , it wont be anymore , maybe one day he will miss the son and will feel regret .
coz of u r far it dont help , try to send him always thru his mail fotos for your son in different days , how he looks like , happy or not , sick , ,,,,,,,
