Relationship issues. Idk what to do anymore

Me and my partner have been together almost 6 years, lately there’s a lot of arguments more than usual and a lot of the time I’m sitting there crying and thinking how did this come to be and if this is all my fault or if it’s normal for the things he says and does like today everything was fine we both had a long day at work but both came home happy at first at least and yes it may be because we’re tired but this happens on our days off as well but anyways as time has gone on after we had got home he had asked me to just get up and go fetch him something to eat and I said dang where are your manners and he was like just get me something I’m hungry even though I just made him food an hour prior and now we have been arguing because he said we were going to hang out together and just have some us time together and then he just puts on some show he wants to watch knowing I don’t care for it and I and I was trying to talk to him and he kept telling me I need to shut up and leave him alone and yes I kept talking I know how stupid am I but anytime it’s the other way around and he has actually done this me me as well he will keep bothering me but now that’s it’s me doing it he is getting mad and getting a bit aggressive and then kept saying not to touch or talk to him he is busy and i understand sometimes he needs his him time but when he tells me we’re gonna do something I expect him to keep his word just like how me holds me to every single thing i say and whenever I try and stick up for myself and tell him I don’t like feeling like he thinks he has control over everything and can just treat me the way he does for no reason he always says I could always leave and I’m like I’m not saying I want you to leave I just want you to treat me with respect like I do to you and he just then and goes and starts saying he rather just leave if that’s the case and it just bothers me and now his friend just asked him to play video games and he stopped what he was doing to play… I know most will say just end it but it’s hard like I wish I could explain the feeling and I know I’m probably not the only one to feel this way I just need some insight or advice or even someone to talk to also sorry for the long post I probably could write a whole book with our problems 😭 anyways thoughts?
