Aita? I need help I don't know if I’m in the wrong or if this is truly a disrespectful?

Me 21(f) my best friend 23(f) have been close friends for about 8 months. We are ying and Yang. She is very cold (black cat) I am more like a poodle sweet but can be fiesty. We usually get along but this has been really bothering me lately. I am talking to this guy, and have been for 3 months I really like him. (19) m. I told her about 2 months ago I wanted to introduce them and us all hang because this was fresh into us talking. She didn’t want to at all, but he said he’d bring a friend. He brought the friend (20) m. Long story short he asked for his friend to have her # I gave it to him and she wanted nothing to do with him. I pushed her to give it a chance. Fast forward she did and now they are dating and me & the guy I’ve been talking to are still just talking. I’m happy for her, but what i hate more than everything is that I think she likes the fact she has something I don’t and constantly rubs it in my face saying “ we are more mature than u guys and we have something u don’t.” And constantly tries to belittle me. For context I am pretty popular and used to promote for clubs and have a social media presence. Whenever we are out, I usually am the one that would get attention, but I mind my business wheveras she is a little looser than me. & does not get as much attention ( I’m pointing this out just for context). I also have not slept with the guy I’m talking to for morality reasons. Wheveras she tells me about her sexual adventures with her man. Besides the point I love her, but I wish I would of never introduced them. Not only did I lose a friend bc she’s always at his house, but she has changed. I’ve always been supportive of her, but I’m sick of her trying to always one up me and act like she’s better than me. Ik this is all over the place buf I just need other’s opinions

To add more context, previously she never had liked any guy I’ve talked to (2 since we’ve been friends) the guy I am talking to is respectful, and wants to go slow. He respects all my decisions. She will constantly belittle me and him say we are immature and “ I have trauma I need to deal with” I come from a stable home. She tells me I’m still a child. ( anyone that knows us, agrees I am more mature) She does not come from a stable home. I am always supportive I just needed to vent
