I, (13+F, don't want to share my age but I'm still in school), am not religious and am (very openly) bisexual. Recently a girl moved from another country to the school I go to, and she's in my PE class. Since she didn't know anybody there, I tried to be friendly, and at first, we hit it off fine. We had the same interests, although she did call my love for Pokémon "childish" and "weird", which I brushed off.

Later I found out we were in the same lunch period, so I invited her to join me at my table with my one other friend. That's when I learned she was Muslim. No, I have no problems with that, but that is relevant to the story. At lunch she constantly asked whether what I was eating was 'haram'. I told her no, I had no meat that day so I assumed everything else wasn't bad. She still was concerned and told me to check next time, which I didn't do because my family doesn't really care about whether what I eat is 'haram' or not.

The next PE class we had she asked me what my sexuality was. A bit strange, but I had no problem answering. After I told her she grew really quiet, and then asked me if I was lying. I said no, confused. Then she practically begged me to be lying. I asked her why and she told me that being anything but straight was a terrible form of haram. I told her I wasn't Muslim, so it didn't matter to me. She asked me again if I really liked girls too, and I said yes again, a bit annoyed. She started laughing as if it was a joke and said I was 'disgusting' for liking the same gender as me.

The next class I felt oddly disgusted at myself and also didn't want to interact with her. But she came up to me and told her that her dad said that either I stop being bisexual or go to h3ll, and also said that her dad said being friends with me would make her 'haram' in the eyes of their god as well. I said I couldn't just change that, and she acted like what I said was a joke. I tried to avoid her that day.

Later I literally had a breakdown because I felt so disgusted with myself for liking girls too, and realized that she was hurting me by saying that being myself made me 'disgusting'. So I stopped talking to her.

A few days after I started ignoring her, she came up to me and asked whether I hated her now, whether she had done something wrong, all while making the most pitiful face she could. I told her I just didn't want to speak with her. She got upset and walked off.

Now we don't speak anymore, but the issue has resurfaced as she's trying to get my friends to be on her side and see me as someone who abandoned her or something like that. So now I'm wondering; was I really that bad to her?

I don't think she should have said something like that to me for being bisexual, but then again, I'm not aligning with her religion, so maybe I'm being Islamophobic by not accommodating for her beliefs. I understand that she was raised somewhere where everyone views LGBTQ as a sin (at least, that's what she'd told me), and maybe I should have been more accommodating and aligned with what she believed. So, AITA?

EDIT: About the lunch situation, it was more because she wanted me to share my food with her and for us to trade foods, and less because I wasn't checking if it was halal. I do feel like that played a part, but she was specifically asking because she wanted to eat some.
