Here you go FlutterbyFotos, I'm giving you a {{{{BIG SAMSON HUG}}}}

Poor dear girl....I have been there too.  You have to work with your state child support agency.  Communicate with them regularly (and more importantly in writing) to do something about the non-support.  Write your state's governor as well as the state governor where your ex moved to if the child support agency seems to have put you on the back burner.  Your ex can first lose his driver's license for non-support...and, if he's six months behind without a single payment, can then be liable for a jail sentence.  Its a long tedious battle when a parent does not honor their obligation but if your diligent, he will be forced to pay (plus interest on the arrears).  I did not receive barely an iota of the child support due me until well after my two sons turned 18.  Child support obligations do not go away if you keep the need alive AND kept regularly and politely in the eyes of the authorities designated to assist in such matters.  My ex spent 6 months in jail for non-payment and when he refused to work while in jail...they sentenced him to another 6 months.  He got the message then....I now receive weekly payments ever since.  Altho, my assistance was not realized until my sons were grown, I was able to help them buy vehicles to drive, pay for schooling (my youngest is dyslexic and had to attend boarding school for three years to be remediated for his learning difference....the oldest went on to university), a trip to Disney World that we could never afford or dream of while growing up, etc., etc.  I hope this is helpful and hopeful for you.  I look back and wonder how I did it all....but I DID manage and even bought a house care of federal funding for low income families when my boys were young.  The help is out there.  I'm happy you have the support of a caring new partner too.  Good luck.  Stay strong.  Hugs.
