Dallas, whomever told you forgiveness means never bringing it up was a moron.... sorry if it was someone important to you. But they are just dead wrong.
Namaste, I'm almost 6 years out, and I've wrestled with those same feelings from time to time. This is what I did.... I would sit on it for a little while. I would try to figure out what was really going on, what was making me trigger or think about the A again all of the sudden. Most often, it was nothing A related at all. The A was the reason for so many of my negative feelings for so many years, that I forgot that I could actually have bad feelings about other things as well. So it became easy and comfortable to "go to" the A when I was upset. I had to teach myself how to not do that by talking to myself and figuring out what was really bothering me, and why.
Sometimes it was actually the sadness from the A that was bothering, but most often it wasn't.
I also took this time to work on moving quickly past my triggers or feelings. Not ignoring them, not pretending they didn't exist, but I would spit out a sentence or two to my H about what was bothering me A wise, and then I would change the topic and life would go on. I got to get my piece out, and he was aware it was bothering me, but we were both aware that it wasn't really a major issue for me anymore. Just a niggle, if you will.
Do what feels right for YOU, that is what matters right now.
