I (M, 19) have been playing with my old friends from high school after my GF (also 19) went to sleep and disconnected the call. After 20 minutes, she called and I immediately went on a VC with her and told her that I was playing with friends because it's been a while since we did that and it's vacation time for me. She immediately said: "Oh that's alright, goodnight". After a while though, she has messaged unsavory stuff regarding my friend group and how I'm prioritizing them more than her. For context, it's been more than 2 months since my last VC with them until just a few hours ago and I thought that would've been fine. It was not. She immediately got unreasonably (I think) angry at me and thought it'd be fine to say those things and telling me to pick between her and my friends.

Now, I thought that it should be fine to have friends and also have a romantic relationship and I believe that it is also healthy. She has her own friends, but I believe her to be unsatisfied with them. I also tried to connect her with my friends, but she was not really keen on connecting with them even though most if not all of them were alright with her. I tried to reason with her, which meant me basically asking her if "is it that bad to have both you and my friends in my life at the same time?". It felt stupid, and it shouldn't have been a question to begin with (for me anyway). I defended my friends from her claim of them being parasites, and how they don't want her in their group anyway.

Because of this fight that didn't even need to happen, she said that she's breaking up with me. I told her to maybe wait a month and we'll see where this goes but she didn't respond to that greatly. The reason why I didn't like this situation is that a few months ago, she did mention to me that she'll tell everyone that she's pregnant even if she's not, and other slanderous claims. She's also told me that maybe she'll kill herself if we break up, which was not really the best thing to know.

After said stupid fight, I asked my friends on the VC if this is just bad. And they immediately reminded me that my ex literally has the same tendencies, to some degree. They advised me to break up with her, and I also thought that it should be my best course of action. AITAH for considering this?
