Look, bottom line is it is a few days after your D. You are going to keep making attempts at inappropriate contact and maintaining inappropriate expectations for some time.
But, when you catch yourself doing it (generally agonizing over some interaction is a pretty darn good sign), then stop it for your own sake.
The more you stop it and keep things to purely business, the better you will feel. At some point, you'll find anything more from him very intrusive, believe it or not.
