I'm glad you got a little peace from the ADC with the song "You Were Always On My Mind." No, it probably can't take away your pain and hurt, but it sounded a bit like an apology. I agree it is a start, and I would keep talking to him.
Sometimes it is very hard to forgive. I know I often have a problem with that myself.
As my mom lay dying of cancer, she told different family members that she forgave us. It felt kind of odd, like "What did we do that we need to be forgiven?" There's a Bible verse that says, "For if you forgive men their trespasses (sins), your Heavenly Father will also forgive you. But if you do not forgive men their trespasses, neither will your Father forgive yours."
Mom was a religious person, and I think she wanted to make sure SHE was forgiven when she got to Heaven! It's hard to forgive sometimes, but God does help us to get over these hurts, when we ask Him to help!
