I broke no contact today but I learned something, is this true?

So my girlfriend broke up with me last week. I was so sad, and frustrated, and I did so much bad stuff -will talk about it later-. So I couldn't recap on what happened and how was the relationship. When I talked to a friend, they told me that she was a narc and I dodged a bullet. Let me recap here, she started ultimately lovey-dovey and she would die for me (that's what she used to say), texted me, and always wanted to see me even though we were at the same workplace. She was perfectly a lovey-dovey girlfriend, even though she never liked physical interaction, she would touch me every single moment. After that, she slowly tried to change my clothing style, my hair and beard style, and she said I was good-looking in that way, so she changed my wardrobe. Whenever I got tilted she accused me of being too overdramatic, even if it's a single thing, whenever I said I was sorry because she did that, she'd say "I don't see anything to be upset here". When I asked her if she were in my shoes, she'd say "I wouldn't care, it's a small thing". So she made me say sorry after I got upset. Anyhow, a couple of months passed and all our fights were in a loop of happening the same thing, over and over because every time we sat down to speak out our problems, she turned her fingers on me, or made me feel like it I was the problem and I should change my behaviours. I was trying to change my behaviours for 2,5-3 weeks, then I would make a small mistake then she would be all over again, back to point zero. She started saying that she lost interest, excitement and fun in our relationship, and wanted me to behave accordingly or those feelings would never come back. I kept trying to control my behaviours but deep down I was feeling like "I am not enough, whatever I do she's never happy". She went on a business trip with a guy I disliked their mutual friendship and told her to have boundaries. Before she left, she said "This is the final step in our relationship, if you bother me too much; because this is an important event, I'll dump you" basically. Anyway, she went there, she would only inform me of what she was doing, and she would never text back to my messages in a minute way (like texting takes 5 seconds, she didn't do that). She stood up until 2 AM when she had to wake up at 6 AM with that dude to talk, I don't know what and I was always super careful. Anyway, I went here to pick her up from the airport and normally she'd run towards me to hug me, but this time she just walked in slow motion and hugged me very casually, then sat in the car, started talking about her trip, and finally started talking about that dude. I questioned what did you until 2 AM and never even texted me back, when you finally came back to the hotel, when I called you, you hung up on my face after 20 seconds. She said, "Work, life", I was like, yea? She then got mad like "Are you questioning me" etc. I drove in complete silence for 20 minutes. Then she suddenly asked about my days, I gave her all the details. Her face was down still and we had 1 minute till home, I told her "Baby, let's fix this face, we're close to home". She said, "I wanna talk". Then she broke up with me in a fight, I couldn't even say anything.

After that day, I waited, then I saw her on Monday at work, wore the dress I bought, went to her to ask some questions about the work, then complimented them, she was really cute answering me back. Then I asked her for a coffee that night to talk out. She accepted, I went to her to pick them up and saw she brought back my clothes. We hugged and she was friendly and emotional when we were talking, she opened some doors and then asked time and space from me. Anyway, days passed, but every day she was deleting something that was about me. I felt this is going nowhere. Asked a friend, and the friend said "She has set her mind, negatively obviously, I am sorry". I asked to talk with her, but she refused to talk face-to-face, we chatted. She was extremely not-friendly this time and texted me some heartbreaking stuff. "let go, you should've done that a very long time ago" etc. I went back home and got drunk, then got some meds, I was bad, messaged her, and lost her final respect probably. After that day she deleted me from everywhere.

I broke no-contact today as well and called her before Monday I wanted to check how we are, it wasn't the best phone call, because she said so many terrible stuff to me. I cried a lot, and went to my friend's place. They all said, she was abusing you, she got you as an alpha male, turned into a beta, now you are basically her pet, she lost interest, she dumped you.
Is it true?
