Welcome to the forum! It sounds like, from your initial description, that you may have suffered from "convert burnout." THere have been several threads dedicated to that phenomenon here. If I may be so bold to ask, what prompted you to go back to the RC only to reconsider the EO later? As long as you have an honest answer, then I think you will be fine. I just hope that you don't end up "swiming the Tiber" again five years down the line. It doesn't matter which jurisdiction you choose, but make sure you have a good relationship with the particular parish and priest that you decide to go with. I don't know if you would need to be rechrismated, reexoricsed or what. I have a feeling that the ROCOR would be more likely to do that than the GOA, but I could be wrong. Good luck to you.
