Professor, you're reeeeally letting Bobbie dictate this conversation. I thought this was going to be your big stand! Your scramble to the moral high ground! What happened to the uncomfortability? And what is this "you need to keep up your strength" business?? Now I definitely think you had sex between Monday and Tuesday, which is just a sloppy way to end things. Clank clank clank phhsss indeed, Professor.
Look, honestly, I don't have a problem with Bobbie's marital status if that's the kind of relationship she has with her husband. It's more that I think she's deeply crazy, and that come on, the Professor has way too many hang-ups to go through with this.
