AITA for calling the cops on my friend?

(Sorry for the rant I just need to know if I’m the bad guy for this, she blocked me saying she hated me and could never forgive me for this. That I ruined his and her life and that I was blowing everything out of proportion.) For some context I 19(f) had been friends with this girl M 19(f) for almost three years now. We were complete opposites on most things but we still bonded over shared traumas and gossip. Recently this year in early march she started rekindling with this past fling H 23(m) and things were okay in the beginning. In the past she has went back to situations with guys who were abusive in some way or the other and when the relationship was over she would repeat the cycle going to the next. This guy I knew little about except they ended over some petty fight. When she had told me in the beginning they started talking again I was supportive and joked around on going on double dates with my partner D 19(m) and had met him once or twice. Their relationship was bumpy from the start starting with name calling and very heated arguments, he would body shame her and make fun of her on what she wore, how she did her makeup, and who she was as a person. When I would FaceTime her to catch up he would say rude statements to me and accuse my partner of cheating on me when I would call out his behavior. I distance myself a bit because I didn’t like him and because she wouldn’t listen to my warning that he was bad news. It started escalating from there where he would roughly grab her to the point of bruises on her, him yelling at her, and throwing objects around her when he was angry. She would tell me what he did crying and scared of what he might do then hours later say it wasn’t a big deal and she was being overdramatic. He was really jealous and would grab her phone to look through it then scream at her if he saw a new guy had followed her. Yesterday is when things got as bad as they had been through the duration of their relationship. He got mad at her for following an ex fling and started screaming at her. I don’t know the full context but she FaceTimed me to tell me he had beat her up, she has lacerations on her neck as well as strangulation marks. She had bruises across her body and her cheek was starting to swell from being punch, she had another several scratches on her arms and hands and he had shattered her phone. He had thrown her phone because we called a couple minutes before the whole thing happened and was mad she didn’t tell him who it was right away, the whole time whispering it was getting really bad and she thinks she’s done this time. When she called me back all these events had occurred. For some added background on their “relationship” he never formally asked her to be his girlfriend so they were in a “situationship” of sorts the relationship progressed really fast and they were planning to move in together in the next two weeks thinking it would fix their relationship. He also was caught numerous times messaging girls and talking to exes behind her back. All of this happened within the span of five months. When she hung up the phone with me I was cooking in the kitchen and my grandma had heard everything she was aware of the abuse that had been happening before this call and urged me to call the cops. I was nervous to do that previously but this was the worse I had seen her from his abuse and was worried for her safety. I asked her to send me her location and once she did I called telling them what I knew of their relationship and how he had just beat her minutes prior, the location wasn’t precise but I gave a rough location with what I could figure out and they said they would send deputies to go check. Twenty minutes go buy and she calls me back screaming at me why I would call the cops because I “ruined his life” by doing so. I told her I was worried for her safety since he has recently gotten out of prison with a charge related to a firearm. She screamed at me how I ruined everything and that she was really going to leave him this time going on to defend him and that she was being overdramatic on him beating her despite the clear evidence he had done so. The next couple hours are a blur, he apparently ran and they now have a warrant for his arrest. I had a recording of him screaming at her that he doesn’t care he broke her phone because if she just told him who she was on the phone with he wouldn’t have done that. Now she’s saying I’m a horrible friend and said she never wants to talk to me again and has blocked me. I’ve asked my partner and grandma if I’m the AH and they said I did what was right to protect her. But I just want to know from an outsiders perspective, AITA for calling the cops on my friend?
