If you plan on staying separate, then you do not need to drop the PFA. There are volunteers at the Allegheny County Courthouse that will discuss your options with you. You can work with them to determine if it is best for you to keep the PFA, modify the PFA or drop it all together. If the fight was serious enough to lead to a PFA, I suggest that my clients consider modifying the PFA and not withdrawing it. I have attached the link to the PFA section of the Allegheny County Adult Family Court Manual for you to refer to.
