Can one forgive and not forget?

Somewhat philosophical question...but one with definite real-world applications. Those of you reading these posts know that quite recently I was not treated with the respect and courtesy one treats a friend. In fact, one could say that the person treated me disloyally. I've come to accept that this person will never change, and that I need to make modifications as to what I share with him. Sort of downgrading him into a lower class of friend.

Now, I know that sounds kind of harsh, but think about it. If you're being honest with yourself...you know that in your group of friends, you have some people you tell everything. BFF's, for example. And other friends...well, they might not understand, or they are gossips--whatever. Regardless...while they are "friends", they are not Best Friends Forever.

So anyway...back to the story. I've downgraded him. Friends need to be there for each other, to generally have the other's back, to support, and to be supportive. They are people who you have a great deal of trust, and vice versa--they have to be able to trust you. And I don't think this person fits the bill.

It's funny...I was busy and hadn't talked to this gent in a while, and was asked if I was mad...and I was going to answer honestly...but then I decided--what point would it make? Or more to the point, what point would it serve? The "30 pieces of silver" had been exchanged, so to speak, and there really was no going back. An apology would not have been able to rectify anything, and wouldn't change the fact that I now have to keep things from someone who was a close friend in fear that it'll be used against my emotions, feelings, and interests.

So back to the question...can one forgive and not forget? Can one absolve a person for something they've done, and then act like they've never, ever done it? Because honestly...I can forgive...but the last part is damned near impossible.

Any thoughts?

Re-evaluate the command structure of this friendship....

Star Trek: The Next Generation...there's a scene where Riker (who is the first officer/2nd in command) is having a discussion with the Captain. Captain Picard wants some info from him, but Riker can't divulge it because he's been ordered to keep it a secret by some admiral. Naturally, this doesn't go over well, because the safety of the ship is at stake. Picard admits the futility of this, but says that "If his trust has been misplaced, then he'll have to re-evaluate the command structure of this ship".

For all of you who aren't ST:TNG fans..that pretty much means Riker is gone from the ship.

The reason I mention this is that a friend did something that I didn't think was kosher, or something a friend should do. Was he within his rights? Yes. Did I end up feeling like crap because of it? Yeah....and I'm probably more upset at myself for giving someone information that was used against me because I placed trust in someone that was clearly misplaced.

So what to do? I've decided that from now on, certain things I'm going to keep to myself. Which is sad--friends are there to confide in, not to be concerned that they will use information against you. One shouldn't be worried about being read your "Miranda Rights"..."Yes, you can tell me about so and so, but anything you say may be used against you". So yeah...it's sad...but probably the best possible course of action...
