what to do!!

Likely you will need to amend your petition for divorce to add a request that the Court confirm paternity of the child since the child is not technically a child of the marriage.  You can provide a certified copy of the acknowledgement of paternity as an exhibit to your petition.  Unless someone challenges the AOP the Court should confirm paternity.   It seems unusual that the Court would deny a TRO due to this situation, but some Courts are very particular about the pleadings and require you to be very precise in your pleadings.
