My online friend keeps making me uncomfortable and I don't know what to do anymore

Hello, I had a friend for almost 6 years now that we'll call J. I met them somewhere in 2021 from mutual friends. When I met her well.. him during that time (because she was homophobic at the time) her was always rude to everyone especially me but since I was quite young I didn't care, I just wanna be her friend. So I reach out to her, she was rude about me and disrespected my boundaries (I know it should have been a red flag but I was young and dumb) but I let it aside, when I came out to my friends as a bisexual person they all supported me except for her saying Its just a phase and she can change me. I was annoyed but I still considered her as a friend.

We actually even dated but it was toxic and controlling our relationship wouldn't last for more than 1 month before he would say bad things to me and then she would come back after a month or two. It was so bad that she even left me for someone else once and I couldn't even careless I was just tired from school. That went on for 3 years. I also admitted that I was angry with the way she treated me back then I manipulated her and kind of messed with her as a revenge. I rejected doing that I blame my younger self to even considering coming back to her as a friend instead of just blocking her forever.

Somewhere in 2024 she suddenly came out to me as a femboy and trans I was kind of weirded out because I know she was homophobic when we met, so I ghosted her for months before coming back it was a stupid decision I know but I couldn't just left her, back in early 2022 I was always by her side during the time she gets bullied at school and times where her family is just absolutely shit about her that she wants to k*ll herself and even hurt themselves too. Especially last year I think she came out to her parents as a trans female which ended up her getting kicked out multiple times in their house, I stayed and felt guilty for not being able to help because We're very far away. So he ended up doing Dr*gs sm*king and selfh*rm because of this until she met another trans male that I'll call E, e wasn't really part of my life much I never talked to him before but my friend J always talked about him, different things but especially about s*x I was uncomfortable with the topic but I never said anything because I knew it was normal for couples and she insisted that were "best friends" I also had a boyfriend and ofc being careful about my own body and love life I thought to tell her about my innocent love life how I told her we never had s*x and wanted to wait until marriage.

She insisted that we should had s*x but I said no because it's risky and I'm still young and then she starts getting sad how I already lost my virginity even tho I haven't lose it yet. And then she keeps sending me reels of perverted things like "the only apology I'll accept from you" and it's about giving them a bl*wj*b. I got uncomfortable and I said I'm not doing that because I have a boyfriend, but I would if I was dating you then she asked "not even as casual?" I said no because I don't wanna do that then she starts getting upset over it. She sends more like "I goon to you twin" it made me so uncomfortable. She keeps h*rting herself that makes me stay but she makes me soo uncomfortable with these jokes. Yesterday was her birthday I didn't manage to congratulate her because I was busy at school but I did congratulate her in advance then she got mad and said I go fun with my boyfriend instead. Please I need help I don't really know what to do anymore
