Good luck with reporting her,then you can get on with your fantastically happy unembittered life safe in the knowledge that you have done your bit by reporting her to the authorities for your perception that she may be claiming illegally for your disabled kid.
Amazing this forum is mainly read by sad women who say im the bitter one,well let me tell you my ex wife was and still is the bitter one with out going into to much detail we have a long drawn out saga of hate and revenge.I am self employed and have lost all my work contacts due to her trashing my buisiness it is only what can be described as war now she has allways said that i would live to regret the divorce and she would make my life hell(now who is the bitter one then) !!!!!
you say that this forum is read mainly by sad bitter women how do you come to that conclusion? is it because it is only the women that have posted replies,
because im sure that in my mind the way you are going on you deserve every thing that is happening, the old saying "What you sow you reap" give it up move on and just get divorced you will be a lot happier and do doubt your ex and ofspring will be too.
i wouldn`t dream of "Grassing" the ex no matter what she is or has done, if i was
you i would go nearest telephone box and have a drink with my mates and calm down
