<human>: Give me the gist of the text in a nutshell

My girlfriend and I fight like every other couple. It's not too frequent, and we don't want to break up. 

But this past weekend we had a big, big fight. I used to have quite the temper when I was a kid (10-15 years old) but got it under control and haven't had any outbursts since then.

In our recent fights,however, and especially the one this weekend, I have been getting so mad that I have reverted back to my 15 year old self and yell, very loudly, without listening to anything she has to say. 

She says it's verbally abusive. I have tried working on it--we had a fight about two months ago and I felt like I was going to start shouting and I took a step back from the situation, everything was fine--but this past weekend was a step in the wrong direction. 

How can I work on controlling this anger? Why is this behavior, that has been so underwraps for years, coming back? How can I fight more constructively?
<bot>: I've been losing my temper recently, like when I was a teenager. How can I control my anger when me and my girlfriend fight?
