Things happen for a reason. It's great that your former spouse apologized and that you were able to listen.
My dad wanted me to know how badly he felt all his life for what he did to me... I didn't make it in time to hear it from him, but he gave that message to my brother.
It was nice to hear, but unnecessary. My need for validation disappeared when forgiveness came. Isn't strange.. what I thought I'd always want (my dad apologizing, hearing that he suffered emotionally from what he did) I didn't need when I no longer harbored anger, bitterness, resentment. All I cherished was knowing that I had a daddy, that I was finally allowed to feel the love that never felt safe to express.
As we progress on our journeys, our growth what we thought we'd need is replaced with the joy of what we have.
