I was talking about the most recent incident.

About 10 years ago, it's ok if he chose not to forgive, then divorce.

But they didn't, and they lived on, had a child, and then 5 years past. You can't say she didn't regret and didn't try to make the best out of their marriage.

And this last incident when he saw an email address, could just be one email that she was hesitating to write. Maybe just to reply to his. It is not the same as betraying her hu*****and.
