Maybe my line of thinking isn't quite right, but I would be inclined to wonder why exactly you want to know how many times and with whom? How important is that information? I mean, do the sordid details really matter? Wouldn't that just make you hurt more? To me, the bottom line would be that the act of betrayal was committed at least once and as the others said, that would be all I would need to know, damage done.
I'm really sad for you to be going through this...been there, done that and can relate. Take care of yourself.
