Is it bad to sometimes be too forgiving towards others that never apologized?

Even since my early 20's, I've been friends with some people that were jerks in their early teens. Till this day we've never spoken about the incidents. They never apologized and I never demanded an apology either. They all seemed to talk about all the great times and somehow have no memory of any negative ones. I'm the only one that remembers it, lol.

They greeted me as a friend and well I went along with it. I've been invited to some parties and I guess moving on is part of life. I just feel like talking the person in the present.

I know not everyone reacts like me. What do you think? Is it bad to be that forgiving if they never apologized and likely never will?

I will only mention the incidents if any of them decides to open up about that topic and asks me about it... then ok.
