ROMB, don't worry about what your H thinks about you re-joining FB. Don't worry about that he doesn't like that you're hanging out with some people he doesn't know, either. You certainly don't need his approval. He isn't asking for your approval for anything he's doing. Also, a little bit of mystery is not a bad thing right now.
Try to find something fun to do while you're H is at the outing you were supposed to go on. You may even want to post on FB on what a good time you had doing it, too. I used to avoid FB, but now I'm starting to take LP's (LearningPatience) approach and that's to use it as a PR tool.
