In addition just because one forgives someone that does NOT necessarily mean that you pick up the relationship where you left off.
What does it mean to forgive? If you don’t go back to the same relationship as before, how are you “forgiving”?
Why is it important to forgive? Not forgiving keeps us chained to that person forever. It takes a lot of energy to hold that grudge and be angry at someone. Choosing never to forgive someone means that you are forcing yourself to remember that person and choosing to be angry at them consistently reminding yourself of what that person did to you. “I will never forgive “x” for ……. and so on. This is a daily process almost from waking to going to sleep.
Says who? I can choose to ignore a person I feel did wrong to me. Doesn’t mean I think about the person at all. I don’t have to conciously forgive the person, I can just cut that person out of my life without ever having to give him/her another thought.
