sounds like your backslide wasn't that bad too me. Who wouldn't be upset with seeing that when your expecting he was done. Although, there's the key... "expecting".
If you bring up the subject again, I would make it as quick and direct as possible. Perhaps you could even ask him what he was planning on doing different to build your trust for him back? I would tell him that the real problem is what you are both expecting. You had assumed he was done, which meant absolutely no non-related work contact, but he wasn't. So perhaps ask him what he thinks you should expect from him.
That's how I always brought stuff up, if it was touchy. I would ask H what he thought was appropriate/right. Then he wouldn't immediately be on the defensive.
anyways, I still think you did pretty good though... the text comment was overdone, as you were just trying to make him feel better, and you weren't being 100% honest... because you know you haven't gained ALL that trust back.
