I'm sorry, OP. There are a lot of things that remind me of my husband's affair. When he has to work late (does he really? he claimed to be working late during the affair...), when I drive by Chipotle (apparently, that was a place they met, talk about classy, and I actually liked Chipotle), when certain memorable dates go by, etc. The world isn't going to change. Chipotle is still there despite the food scare earlier this year

My husband has a job that in fact does require a lot of hours. The reminders fade, but I'm about a year out. I find that I am just now getting really angry about what he did. Strangely, it bugs me a lot that he has gained a bunch of weight back. He was in tip top shape during the affair but before and after he was/is quite pudgy and lackadaisical about his hygiene. I guess I'm not worth the effort. It really pisses me off!
I think the champagne thing will fade with time. I often wonder if these "triggers" would disappear if I got a divorce, but I doubt it. So I think leaving wouldn't fix anything about that specific problem. I have to say, my husband apparently doesn't think about his affair that often anymore (according to him) but it occurs to me daily still. I have no clue if our marriage will make it, but I'm trying my hardest because I have small children and want to make sure that if we get a divorce, I tried everything I could.
