Your convos with your H sound good. Keep it up. As for your comment about the undesirability of a D, I would just make sure that you stay away from the topic from now on.
Make sure you seem like the better choice by staying calm and applying DB principles to the letter. It sounds as if he was a bit thrown by the fact that you had plans for the evening. Keep that up.
You're on a good path. Keep going.
