The best quote I’ve seen was one posted by Burgbud I think. Lil used it on her sig line for a little while, something like
Forgiveness is giving up all hope of a better past.
As you say, not forgiving is to hold on to resentment and anger. For some it is also a control mechanism to purposefully keep a wedge in the relationship to prevent too much closeness. My wife does this.
I think there can be an unexplored, unexpected "leap of faith" power to "letting it go"....
I agree, but only if there is not too high a level of fear to prevent such a leap of faith. My wife cannot make such leap because she has been too traumatized. She cannot/will not place her faith in anyone other than herself.
