If the original agreement as stated in your inital post was a one time affair for each and both agreed not to let the other know then it appears the rules somehow got change. You susequently posted that you are aware of her recent affair and her looking to hook up again with him. If this is the case, she appears to be taking this in a new direction. Perhaps you need to review the initial parameters and take a hard look at where she might be going with this. If not you just might have all the time in the world on your hands to choose who and how many affairs you want to have.
