I think you owe it to yourself to carefully examine what is happening here and why. Since childhood, you have been living a way that was expected of you, and you were unhappy. You began looking for answers in religions, two of which you have cast off in the time I've known you. They didn't satisfy.
Your present religion, an Abrahamic religion, will attempt to dissuade you from your thinking. Already one believer has told you how uncomfortable this makes him, and he considers you confused in a negative sense, as in mistaken. Another warns you about trusting feelings, which he puts in scare quotes, and he no doubt means the ones that contradict his religious sensibilities. Your fellow Baha'i will not encourage or congratulate you like most of this thread has but will also try to herd you back into the fold. One describes leaving that path as failing and being faint-hearted.
And please notice where did these good ideas that make you feel whole come from? Not these religions. Probably your bisexual girlfriend. You've turned from holy book to holy book for answers and found no satisfaction. A new influence came into your life, one all Abrahamic adherents will disapprove of and try to stifle if they can. But her ideas connected with who you actually are. Theirs try to shape you to conform to their moral dicta.
Shouldn't your "religion" come from life and not a book, from experience and exploration rather than trying to conform to one straitjacket after another? I highly recommend a "
Rumspringa" for you - a clean break from religion for a season to look at it again from the outside in and decide if you prefer being within or without. See what a year or two of exploring life with a guide like your girlfriend gives you and compare it to what the religions give you.
Then if you like the change, make your own "religion" from the parts of these other ism that resonate with you. What parts of Baha'i seem right to YOU? Keep those and discard the rest. Likewise with any other philosophy or worldview. That's what those of us outside of religion do perforce. We piece together a world view rather than choose a prefab one and try to make it fit - a procrustean feat for some.
Now THAT'S a spiritual journey, and one that might actually reveal spiritual truths about your own spirit and spirituality, which you will recognize by the way these ideas resonate. You trust your own instincts, which has been difficult for you in the past, but you are learning how to do that now thanks to your girlfriend.
Congratulations and good luck in your journey.
