Forgiving our spouse - How to stop shame and condemnation

It's inevitable that as we move forward in relationships, we'll eventually "bump" into each other's past hurts and therefore end up hurting each other.

So how do we forgive someone so close to us as a spouse, whose actions directly affect us, and who have the potential to hurt us time and time again?

I used to think that by forgiving myself and others, I'd be condoning what I and they did, and setting myself up for future hurt - until I discovered that in fact, forgiveness is the key to change.

What do you think about forgiveness? Do you forgive daily - why or why not? :) :) :)
