<human>: I'm still frustrated and angry but I'm mostly sad. I'm not a violent person normally but I kinda lost it. How do I go back from this? How do I fix this, I need this to stop.

I moved back in with my mom a little over year ago because a relationship didn't work out and finding a affordable apartment anywhere near where I work is really hard. My brother and his girlfriend live there as well, they have their own place but it was a shell, not really livable, and they don't want to take too much loans so they wont move for a quite while either. 

I guess its frustrating for all of us but sometimes everything is fine and we have the best of times but sometimes when hes annoyed or something he flips this switch and becomes this bitchy diva, fighting with everyone and looking for any and all flaws constantly picking away. Normally I just leave and go to my room. But I was making some food, something small after work, and hungry so I didn't want to leave. I did asked him to leave but he just wouldn't. He was complaining about how me and mom don't pick up after ourselves (Its not bad and him and his is no better).  I tried to ignore it but when he threw a magazine I'd left on the counter in the kitchen at me I got pissed and I pick it up and threw it back at him and I see how he starts to look for something to throw so I push him into the freezer. He flips and launches at me but I push him into the table the table, he falls down (hes not very big...). He yells he gonna call the police and goes to a friends house.

I think he scrubbed his elbow but nothing more and it would surprise me if he sued but its really beside the point because I really wish we had a good/better relationship, but at the same time I just cant take his constant abuse.

(No point asking my mother for help, she never put the foot down ever and I was a spoiled brat as well until I was like 20 when I realized I could do much more to be a person that I wanted to be.)

Summarize the given text in a few sentences.
<bot>: Couldn't take any more verbal abuse so I pushed him around. He is really angry with me and I really wish we could fix our relationship.
