My H's EA was also with an old flame from school, years ago. There must be lots of these kinds of A's since people can find old schoolmates, etc. Sucks, because we LBS's are fighting against a younger image of a time where they were young before all the responsibilities.
Oh well!
I think you're on the right track. Just play it cool. And I like that you're already on your way to forgiving ... that was a hard one for me.
Take care.
