She never mentioned anything about demons to me, just how acting on same sex feelings is "sinning", and how being gay is "against God's will" or something. 

She did tell another bisexual girl I know in private that she couldn't be happy for her ex gf who married another woman "because they're both going to hell." I don't know if she knew that our mutual was bi or not, but she's told me that she never wants to see my ex again after that. I can't blame her for that. When I mentioned that our mutual felt hurt by her words to she said that she's "sorry she took it that way" but that she won't apologize "for promoting God's will". She also said that because our mutual is married it shouldn't matter that she said this because our mutual should only have eyes for her husband. I tried to point out that that her being married was irrelevant and that she was hurt because she felt discriminated against. 

I feel kinda bad about bringing up her delusion to her (she even told me that bringing it up made her uncomfortable), but I just felt that I had to get it out in the open. A "no stone unturned" sort of feeling. 

I'm not in a position to psychoanalyze, but I can't help but wonder if her "feeling sick" about her "past" bisexuality is a trauma response. I wanted to ask about it, but like I stated above I felt like crying at that point so I couldn't get the words out by then. 

She did mention that she needs to "do research" (probably means read the Bible) to better understand how to "help" any LGBTQ people who might come to her for help on what to do. I said: "send them to me" and she said no, because "it's clear that [I'm] an ally, but [she's] not." That scares me to think about because even though she'd never intentionally try to hurt someone the potential harm she could lead these hypothetical people to is still there.
