Following my divorce I became disable. My income has been cut by 60% and my medical expense have increased. Hers income has increased. I receive social security disability, but my x-wife receives the benefits for my son, which I 3 times more than what is dictated by the divorce. I have my son about 35% of the time and have expenses. I am the one with the disability, why is she getting much more than dictated by the divorce discreet
