If she was ready to leave you for him, of course she did.
I understand your need to know. When my first wife had an affair on me, guilt made her tell me one night. I immediately made her tell me all the details. Who, when, where, how many times...all of it. Amazingly, she told me all of it, but was hesitant to tell me who. Turns out, it was my boss. She eventually left me for him. She realized later what a loser he is.
Best "tragedy" that has ever happened to me.
