Forgiving. Is it Really Easier Than Forgetting?

I very recently had a friend treat me, well, pretty badly in my opinion. He didn't actually LIE to me, but he omitted pretty much the entire truth during almost our entire friendship. He was someone who I felt unbelievably close to, someone who I could be myself 100% with. He never once gave me any concrete reason to believe that he was hurting me in more ways than one. First of all, my ability to trust men is already on shaky grounds (what with all of the less than fabulous guys that have fallen in and out of my life) so his treatment of our situation only heightened my level of wariness when it comes to the opposite sex.

My question is, how do you successfully move past this? Is this a situation where the friendship has to be over? Can I forgive him for how he treated me, or more importantly, should I want anything to do with him at all now? If I was talking to a girlfriend and she described my situation as one she was going through, you know without a doubt I would say "Forget him" "You don't deserve to be treated like that" or any one of those supportive phrases we've all used. However it just feels so different when you are put in that position and it's someone who you (even thought you hate like hell to admit it) still care about as a person.

I suppose that I should be the better person and at least keep the lines of communication open. I know that things will never again be the same between the two of us, but at least I have hope that we can at least somewhat rekindle the friendship and be civil and understanding to each other. I'm not sure if he's willing to be on that level or not, but at least I know that I didn't give things a shot and that never compromised myself in the process.
