I am now 2yrs away from a bad relationship of 4yrs which I found out 2006 he was a narcissist ! Could someone please explain to me, how they can be so cold & treat you like they never even met you? We were close friends for yrs , we had great times together, Now just yesterday I saw him, not since 2006 , a part of me wanted to talk to him ? Is that wrong, That he abused me for years I have to forget somehow ? This really bites.

Good you saw him.

Now your brain can relax and make it less of a big thing.

You're done... moved on.. that was a little cherry on the recovery sundae. You were fine.

Normal to want to talk? Sure... you're human.
Normal to actually go and communicate? Not so much... that's seeking trouble.

I can tell you that I wouldn't waste my time if he was abusive. Any man who abuses a woman doesn't deserve her in the very least, even if it is just as an occasional contact. But of course, in the end it's up to you. Do you think he's worth being friends with, and do you think that you're going to be able to be friends with him after the past you've had together?

I think seeing him has stirred some old, forgotten, feelings up again, and your reacting to them. They will fade in time, if you go on about your life, without dwelling on the past.
