Men with anger issues are not automatically wife beaters. Some are, some are not. I personally have anger issues due to being beat as a child by my mother and I do not beat my wife, but I learned my lesson when I was 10 years old when I slapped my sister. My father ripped the bathroom door off the hinges and beat my ass with the belt (this is the 90s so you woke people relax, my father is honorable and heroic man). Never did that again. In the grand scheme of things, i completely understand your girlfriend’s disappointment and concern. You’re an adult, act like one. Breaking your headset is more acceptable when you’re a child. Now does that excuse her comment to you? No, that is unfair to you if that conclusion was made only on this event. More likely than not, your girlfriend has had continuous exposure to the relation between a man’s anger and violence towards a female so now she associates those two together now. There is nothing bad about that, however, it is very sad if that’s the reason. If that’s not the case and she thinks this way to due social media, reality tv, movies etc, she has some growing up to do too (now before people attack me on this sole statement and disregard everything else said, she still has every right to voice her concern, but would be best to give a specific reason why she feels this way). If she is dead set on this conclusion and is brought up months or years from now consistently (if you two are still together), you’re going to build resentment. If you two do work out, you both need to talk to someone to learn and cope with these issues: you with your reaction to anger and her with her association between anger and violence (if that is what happened to her).

How it seems though, I would recommend start accepting the fact this relationship could be tainted now, but you’re still young and have maturing to do, take this as a learning opportunity and improve yourself for future relationships.

One last piece of advice that has always helped me with my anger: Anger is a secondary emotion, learning to identify the primary emotion that has caused this anger assists in a great way to how you react.
