Don't let her off the hook this time. I think she was both wanting to see if you really do that and crying out for reassurance that her efforts are enough to keep you from looking elsewhere. I think it is time that she was told in blunt language that her efforts are NOT enough, personally.
But I also believe in being empathetic and loving and I know you will be able to walk this fine line, Hairdoggie. You do it here every day.
