Aubrey Plaza has done such a great job in this. My heart was pounding with anxiety every time she was on screen and was clearly not okay. Her husband could have maybe been forgiven if he'd come clean right away since he didn't sleep with Mia but lying that many times completely erases that chance. Especially when he doesn't really owe Cameron anything. Even if he came clean in the next episode, which he hopefully does, I wouldn't believe that he didn't sleep with her.
