No need to be shy! I’m no expert, and I’ve only worked with Hermes a little bit, but I’ll try to answer your question. I work with more than one deity, I have basically a patron goddess and then a lot of close relationships with other goddess. I think you can do that and not have there be jealousy between them, I’ve not had a problem with it. Now if you are feeling that way only with the necklace, then I’d do some readings (divinations) about that. Basically: I’m sure you can work with Apollo and Hermes, but maybe dig into that necklace a bit and see what’s going on. Followers?
