So, I need some advice.

I have been avoiding a store that someone works at. My ex was sending nudes and sexting this guy many years ago before her friend got married but was engaged. He never told her and we never did because my ex insisted.

Now that I'm divorced, I have been avoiding the store because if I run into his wife, I know that there is a strong risk that I will end up saying something. It's been almost 10 years since they were doing this, but I also hate holding this secret.

Now, this week coming up, I am going to have to go there because they sell something no local store does. I fear running into her because if she asks what lead to the divorce, I don't want to destroy another marriage.

What would you guys do? Would you tell her or just let it go?
