AITAH for getting with my friend's fwb even though I knew she would be upset with me?
*For the sake of my privacy, I will be using fake names and ages*
I (18f) got with my friend's (18f) fwb (19M), and now she's mad at me. I originally met my now bf (B) through my now ex bsf (G). This all started in September 2025. She texted me about B and asked if I wanted to meet him. I agreed, so we hopped on a FaceTime call, and we all talked for a while. B and I got along well; we both enjoyed similar things. This is where things got odd. I identify as queer, but I'm more attracted to women. I flirt with my female friends playfully. G was showing off her dresses to B, and I joined in on the flirting with her, and he didn't mind. She had to get off the call, so that left B and me alone. We laughed about random things, and he eventually asked about my dating preferences and sexuality. We figured out we were into similar "things"; mind you, he was high off his ass. He opened up about how he really felt about G, that he wasn't into her, and that's why they weren't together. After that day, we talked over the course of a few days (ik, it's short) and he eventually asked me out. I thought he was attractive, but I didn't want to ruin my friendship with G. We decided to get together, but wait to tell G until I saw her in person. Fast forward to about a week later, and I went to her house for a sleepover. Apparently, she was getting suspicious about B and me; she kept asking to see our texts and would ask me questions like "Do you like B?" and "Have you talked to B yet?" I told her, "No, I haven't talked to him, but I do find him attractive, he is a very sweet and funny guy, but I know you and him are fwb". I would also ask questions to get a feel for how she would react when I told her (Ex: "Would there be anything I did that would make you cut me off?" G: "Probably just flirting with B"). I eventually decided that I couldn't keep it covered any longer and told her while on a call with B. She said that she didn't care, but I could see she did, based on her body language and tone. I tried talking to her about it, but she wouldn't open up and kept saying, "it's fine." Anytime I would talk about B and me over text, she would get really dry and short in her replies. I recently found out she blocked me after trying to call her because I left my Ray-Bans at her house. B and I are still together and are very happy, but I can't help but feel a small knot of guilt in my chest when I think about it, she was a really close friend, and I do miss her. So, AITAH for getting with G's fwb even though I knew she wouldn't be happy about it?
