I had to practice forgiveness to let go of the resentments. The resentments were weighing me down. I resented his behavior, yet, the reality is that I have no control over his behavior. He is an adult. He can and will make mistakes ( just as I do too ). He will have to deal with consequences from his behavior, just as I do too.
I had to forgive my A for not being what I wanted him to be. I set him free to be himself. I did this privately. We did not discuss it. It was something I did for myself to find serenity.
