I'm positive about the EA though she refuses to admit it. Even giving her the benefit of the doubt only gets to "she just doesn't see it" so not much help there. I'm less positive about the PA. Though I keep adding 2+2 and getting 4, I don't have any proof. For sake of argument though, yes, I believe that she cheated on me.
I'm guessing you're in the "run, don't walk" camp?
