It can make you say horrible things.
It can push you to a place of despair.
It can make you feel so isolated.
I have heard from far too many people of late who are or have been embroiled in hard interpersonal things. They stand their ground because they have been hurt. But usually, when you refuse to come closer, you hurt the other person more and then they hurt you back, yadda, yadda.
An apology goes a long way.
Like : I can see that I have hurt you and I am sorry for causing you pain. Will you forgive me?
What happens next is up to the other person.
Justification : I had every right to do what I did.
Rationalization : I wouldn't have done that if you hadn't done this first.
Minimization : What I did wasn't really that bad (and certainly not as bad as what YOU did).
These are EXCUSES and they allow you to blame the other person and never own your own stuff.
Reconcilliation : I hate this distance between us. Can we work to really listen? I know I hurt you. And I feel terrible about it. Will you accept my apology?
Please, if its a little thing, or a huge thing; just humble yourself and do whatever you can to make things right. There is already so much pain in the world. You don't need to add to it.
I'm talking to all of us here.
