Grudges and Forgiveness

Are you the type of person to hold grudges? Or can you forgive and forget easily?
Does it depend on the person who commited the 'act' against you? Or the seriousness of the 'act' itself?

I watched a movie not too long ago, and one of the issues at the heart of the movie was forgiveness. The protagonist in the movie was told that when you hold a grudge and refuse to forgive someone, you allow THEM to have power over you.
I can see where this is true. Even if you say you don't speak to someone anymore, at some point it surfaces to the front of your mind. You wonder if things would have gone differently. You try to make excuses for their behavior. They are occupying space in your mind, and it's not good space if you allow it to only be negative thoughts.

I admit, I suppose I used to hold grudges. Now, I might give the appearance of forgiveness. But I do NOT forget. It's very hard, especially when I've been badly hurt by someone, not to think about what they did sometimes. And I know this probably isn't healthy. It's something that I think about every now and then, and I work on it. I'm not perfect. No one is.

The act is no longer brought up. You talk with the person. But there comes the issue of TRUST. Every now and then you do wonder about what they're saying about you, or if they're plotting to do something TO you. You have to work through this too.

I'm not a religious person, but I heard Pastor T.D. Jakes talking on the radio earlier this morning talking about forgiveness. He said if you want to lose weight, try first getting rid of the grudge that you hold...you'll realize it was heavier than you thought.
