AITAH For not wanting to be friends with the people I'm friends with anymore?

I (28 F) have lived a chaotic three years. I have a boyfriend (32 M) and we've been together for almost 2 years. We've had our rough parts, but luckily we've managed to get through them. He is loyal. He treats me well. Im confident to say that I am in love with him. I also have a few friends. They all have a history of trying to get with my boyfriend. Texting him. Telling me they think he's hot. Being too touchy with him. My boyfriend has had to put up many boundaries, and doesn't want to be around them. I stopped bringing him with me to my friend hangouts and they all got really upset by it. They told me I was a horrible person for hiding my boyfriend from them. I found out they all started talking shit about me to each other, and eventually they all confronted me. They told me I was self absorbed and that none of them wanted him and I was acting like a pick me for telling them he doesn't want to be around them. One of my friends got mad at me and we got into a fight one on one over text. I told her I didn't understand what I've done wrong, and she told me I was a terrible person and I made everyone feel like crap because of it. My boyfriend used to have a thing with one of my friends way before we started dating, so I wasn't really comfortable with him being around her anyways (context. Me and her weren't friends until after me and him started dating) My boyfriend thinks I should just drop them all as friends since they can't handle the fact that he doesn't want to be around them. I don't understand if they are in love with him, or why me not bringing him to hangouts is such a big deal. Two of them have boyfriends already and I've asked them why they are being like this and they shrugged and said that their girlfriends feel like I'm creating all of this in my head and that I'm crazy and I think the worst of them. I don't know what to do and it seems like everyone is blaming me for it. So AITAH????
