I think it's difficult to say without more information. My question is do you feel like you could forgive her? She's not the same person she was 10 years ago. Are you in love with and happy with the person she is? Do you think it's possible she'd ever do it again? People do dumb shit when they're young. They usually spread it out amongst a few partners, but y'all never had a chance to make mistakes with anyone else.

It all comes down to how you feel about if you can forgive and move on or not. And that's a really tough question.
