<p>You pulled a knife on him and you threw a chair at him.</p>
<p>You do not seem to grasp that this is a big deal. It’s a really big deal. And nothing he said in any way justifies what you did.</p>
<p>You’re lucky he didn’t call the police and have you arrested.</p>
<p>You will be lucky if he doesn’t either up and leave, with you responsible for paying his share of the rent (since he doesn’t have to live in a home where this kind of thing happens) or get a restraining order to force you out.</p>
<p>And you’re lucky he didn’t defend himself, because you could have gotten seriously hurt or you could have seriously hurt him – and landed in jail for an extended period of time.</p>
<p>You owe him an enormous apology in which you take full responsibility for your actions (and don’t use the knife-pulling just as a way of showing how badly he was behaving, and don’t really complain about his behavior at all, because while it wasn’t good it does not remotely begin to justify your response), at the very least.</p>
<p>You also need to figure out what can you do so that this never happens again, not even once. I’m not kidding. This is the sort of thing that, if it happens once at the wrong time and place and with the wrong people, can derail your life in an enormous way, including jail time, losing relationships that are important to you, serious injury, and death. And if it happens repeatedly it can destroy the lives of people you care about. </p>
<p>Although I’m not sure it’s reasonable to say that someone cares about someone else if the first someone repeatedly brutalizes the second. I’m in no way saying you’re a bad person, but if this is something you repeatedly allow yourself to do when you get really angry, you will become someone that nobody should want to be around.</p>
<p>One place to start might be the student counseling center at your school. I’m sure other people will have good suggestions.</p>
<p>But you do not seem to be grasping what a big deal this is, and that concerns me.</p>
<p>Not only do the people around you not deserve to be treated in this way, but you deserve better too, and I really hope you get help not only for the people around you but also for yourself.</p>
