Forgiveness

So an interesting thing happened yesterday. The detective found my friend and got a testimony from her about the fraud case. And then she called me. She finally wanted to sit down and clear the air. So I picked her up and we talked on the way back to my place. I got to have my questions answered, and have explained what happened to her. I felt a little rattled by the whole thing, but otherwise okay... and definitely happy to be moving towards a resolution and reconciliation.
My mom called that night, and I told her about it. She got pretty upset and I felt like she was chewing me out. Suddenly, a decision that I felt was a good one, was under fire, and now I doubt myself. Am I doing the right thing? The Lord teaches us that forgiveness is the mightiest sword. Just because we sin against Him, doesn't mean he cuts us off forever. Yet, somehow, I suddenly feel like I need validation in my choice to be more Christ like. I just hope my friend is sincere in her coming forward and it's not a case of "Fool me once, shame on you. Fool me twice, shame on me."
