<human>: Can you provide a brief rundown of the text in within 3 sentences?

Simon and me have been together for almost 9 years and have a generally good relationship. He is a well spoken, educated man with a good job, a generally very reasonable person and a good citizen. He is a trustworthy and supportive partner; my friends and family like him. 

However, in the last 3 years of our relationship, he started to loose his temper when we have a fight (generally about cleaning up the house) and do things like: 

- punch a hole in a door with his fist
- brutally throw his (beloved) phone on the floor
- unhook a picture frame from the wall and throw it through the living room
- scream "Fuck you" at the top of his lungs several times, even though I beg him to stop because I'm scared the neighbors will call the police/ am embarassed they'll think I'm in an abusive relationship

Because he never throws anything AT ME, he denies his actions are violent. I disagree. He doesn't see a difference between me saying something perhaps very hurtfull or unfair to him and him destroying our belongings in a fit of rage. 

I don't think he would ever hit me (the only time he apologized for his actions was when he threw his phone on the floor a meter from me; he apologized because he said  it was too closed and didn't want me to be scared), but I feel really hesitant to start a family with him now. What if one day he looses his temper when we are in a car and he's the driver? In front of our children? Etc.

**MY QUESTION:** 
Am I right about the fact that his actions ARE violent and threatening? Or is it normal for someone to react like that during a fight?
<bot>: My SO of 9 years has recently started to throw and break objects when we have a fight but doesn't see it as an act of violence because he doesn't throw them AT ME. Am I right to disagree?
