Boyfriend said he uses me

My boyfriend has bad anger issues and gets frustrated incredibly quickly. All of our arguments are him yelling at me to get his point across.. he can’t talk rationally and with a regular tone of voice. Lately I haven’t been standing for that. He picked an argument with me and got frustrated and slammed a door immediately when he didn’t like my response. I turned it into a big deal because I’m so sick of his patience level with me. I could care less about the argument he was making - I needed to get the point across he yells at me and treats me wrong when he gets frustrated. Well of course he gets even angrier.. i keep stressing my point and he calls me a raging bitch and storms out. I leave the house and he comes after me - all I say is “you verbally abuse me.” And walk off. It was like a flip changed and he was so sorry. It’s like him hearing this snapped him out of his angry fit. Anyways, we finally talk rationally and he goes off saying how he must be such a burden of a boyfriend. He starts listing things off and says I’m a horrible boyfriend, i can’t hold a job, I yell at you, I USE you. I stop him right there immediately and I say I never said you use me..... what are you saying? And he panics and says I didn’t mean it like that, I just feel like I do. He kept trying to hug me and comfort me and then said he was going to throw up and ran off to the bathroom. He kept asking me if this was it and we were gonna break up...... The whole point I was making during the argument was I will not tolerate the way he talks to me when he’s angry - I never said he was a bad boyfriend or anything along those lines. He is ONLY verbally abusive in arguments. It sits with me incredibly wrong that he said he uses me. What could that mean? Is there something behind the scenes I’m not picking up on or was it just a sob story and he didn’t truly mean he uses me. Thoughts?
