Advice Please

Dear Troy,

I love the show. 29 years ago I gave birth to a beautiful baby girl. I had decided to give her up for adoption, but afterwards decided against it. Her biological father wasn't disclosed to her until later years. The father had asked me if he was the "dad", but I lied, there were many family dynamics involved and instead of opening up a potential can of worms, I told him a lie. The problem is now she wants to meet him. She has been introduced to him, but not as father and daughter. Please can you offer me some advice on how to do this? I am lost.
