When me and my gf get into an argument we always get heated so I'm wondering if I've been doing too much. so yesterday my girlfriend (17F) to me (18M) to unpin my best friend (18F) because she looked at some texts between me and her. So basically what happened was last month me and my gf had an argument and it got pretty heated, and during the argument I was wondering if I was in the wrong because we were going back and forth so I went to my best friend, showed her the conversation and asked her if I was wrong and I told her to be blunt with me. After she read everything my gf said, she told me I wasn't and she called my gf a bitch because of the things she was saying to me.

me and my gf were arguing about some issues we were having and the things that we did to each other. When I brought up her pulling my hair and how I still had an issue with it she told me if I'm not going to accept the apology then I need to stfu about it and i also brought up her being disrespectful to me and she told me she gets like that when I 'talk dumb' to her which I still don't know what that means, but anytime she thought i talked dumb to her she got disrespectful or just slapped me.

When she pulled my hair she did it out of nowhere, so I grabbed her wrist and twisted it a little to make her let go and after she did I told her to not do it again but she kept doing it so I got fed up with telling her to stop and twisted to the point where it hurt her. Later that day we talked about it and she said it was a test to see how I would react snd she said I always react the same way to things like that. When I asked her how I should've reacted she said I should've asked calmly which I did at first.

Also a few days ago we were on the phone and she was a little mad that I didn't want to hang out with her that day and I said we could the next day, so during the call I tried to explain why I couldn't and she told me that she didn't care about anything I had to say and she was pretty rude so I just hung up. A few seconds later she called me and we got into it and it escalated, she kept telling me to shut up and suck her dick so I said fuck you to her and hung up every time she said those things to me.

I went to my best friend three times and every time she told me to break up with her because of the disrespect my gf was sending towards me. I feel like every conflict we've ever had was because I was always reacting to something she did or said and a day or two ago she said she felt the same way, do you guys think I overreact or is it warranted?
