I'm not sure of the facts. It seems you are saying you separated at some time, A divorce was filed in Dec of 2011 which was dismissed. In July of 2012 an order was entered (don't know if it was temporary or final, part of the divorce of a new case). When you say you went back, does that mean you are living with him again? It is difficult to answer the question, not knowing the facts. In general, if there is an open case, with an Order to pay, he owes regardless of whether you are living together or not. He would have to go to Court to get credit for the time you lived together. If there is no open case, and the Court order is not a final order, then you probably can't collected if you are living with him now. If you have separated again, then you should be able to collected for any time you were apart that he did not support the child. I hope this helps.
