I got the sense - due to the apology scene mainly - that he's acting polite to lull her into thinking he's actually a good guy/repentant, right? Imo that is fine, to have the MC outwardly acting and saying "vanilla" things, but, just as the apology scene goes, his internal thoughts should still be wicked. If him berating Jane to her face on each scene wouldn't be believable, and you want MC to act normal for a time with her, imo he should still totally berate her on his mind every time he sees her haha.
