Sorry to be so late to the party, I saw this but couldn't answer over the weekend on my phone...
The last time I triggered was at 5 years 3 months (it was such a big deal at the time, I completely remember it)
I had such a hard time because I thought I was done with triggers...but this one turned me upside down. I think because I was so sure I was done with them I was afraid to bring it up to my husband, so I suffered the entire weekend until he figured it out, lesson learned...
So with that being said, I haven't triggered since. We will be 7 years out this summer and I consider us R'd. I don't think about or need to talk about the A, I have put the OW and our friendship in the past. There are no longer any issues that bother or hurt me.
Will I trigger in the future? I can't say.
I can say now, where there would have been a trigger I hardly feel a whisper as I walk through it. No reaction needed, no symptoms in my body.
I cannot remove all memories of the past, so I assume I will occasionally get a whisper here and there, but not even close to the triggers we experienced through-out R.
You are so in tune with yourself and your feelings, I bet yours become even less of a whisper...kwim?
