Was doing so well recently after breakup 2.5 years ago but...

... today he just came into my head and wouldn't leave, and I know what caused it, going to visit a family member who also lives in his town. I just felt emotional driving into the place, even though I have been there since we broke up just over two and a half years ago. We've only seen each other once from a distance since we broke up. He ended it coldly and said some hurtful things to me at the time, after 5 years together, and although it took me a while I felt I was over him now, so I don't know what happened to me today

Is it normal to feel triggered like this a couple of years later?

I’m not as far ahead as you OP, but I’m going to say yes, absolutely. I found myself crying this week because I saw someone with the same bank card as my STBXH, which I know sounds utterly ridiculous to say. I think triggers can happen when we least expect it, and time plays no part. But let it come and let it go, don’t fight it in my opinion xx
