Ben. Noah will forgive you because you are his favourite person in the world. He might feel betrayed right now, but eventually he'll realise all that other stuff you did for him is so much more important. And Andy is just doing what she sees Noah doing. She's sad too, yes, but she'll get over it eventually just like Noah will. And you did not drive Emily away. Or...it wasn't only you. That was the final nail in a huge coffin that would have...been nailed anyway. Oh god, phrasing. You know what I mean. Do you really think you guys would have reconciled if you hadn't slept with Mum? Don't take this all on yourself.

Yes, you probably should have told them. Does it make you a terrible person that you didn't? No.
