Dissolution of Adoption

What is the name of your state? PA

I was wondering if anyoe knew how I could dissolve the adoption of my ex-wife's daughter? She is 21 now and I want to legally seperate my ties. I supported her all her life without question, now I need to resolve a painful situation.

Michael :

To what purpose, you no longer have child support to pay?
You are both adults and free to do as you please, what is the source of your pain?
