AITAH for not talking to my best friend after she got a bf?

I (18F) and my best friend (19F) haven’t talked in months. It all started about eight months ago when she started talking to a guy. She didn’t tell me that she was talking to him at all until about a month after they met. I didn’t even know that they had met. she was pretty much the same she just wasn’t really present when we were together because they were constantly on the phone or texting and a lot of times when we would hang out she would FaceTime him instead of hanging out with me or would leave the room entirely to just be on the phone with them for hours. I kind of assumed it was that she was just getting to know him but after they didn’t work out she kind of threw herself into work. She’s had a really bad past and so she struggles with showing emotion and so I was trying to be understanding. Apparently her and one of her coworkers ended up getting close and they started hanging out separately in the last I heard was that she didn’t like him but he liked her and then the next week we hung out she told me that they had made out. After that things kind of went downhill and she would show up for hangouts four hours late and basically hide in another room the entire time to call him or when she was with us for like 30 minutes she was texting him. Between both of these situations it had been about eight months of her acting like this and worse (which I won’t mention) basically the situation wasn’t getting better and I had mentioned to her that I was OK with this but nothing improved and so I told her I needed a break and we’ve tried to hang out past that but it was really awkward and my other friends were saying it didn’t really seem like she was making an effort to hang out with me and was just talking to her boyfriend. we texted a little bit after that and she kind of said that it seemed like I needed more space even though I said I didn’t and it was just really awkward and she felt like I didn’t wanna be friends with her anymore. I communicated that that was not the case and kind of explained my side but we still haven’t talked since then. AITA for not really wanting to be friends for a while?
