bf problems..

So me and my bf have been dating for a year now and we have been having some problems. When he gets mad it feels like the way he talks to me is belittling or like he is trying to humiliate me. An example of our recent bad fight, he is trying to start his own buisness (not going to say too much) but everyone knows or has heard that if you talk about your future goals too much to too many people they will put bad voodoo on your goal and wish the worst for you. Not sure if everyone believes that but I am a strong believer because that has happened to me. Anyways, he has an interview one day online and I happened to be around listening in a bit. In his interview he was saying his plans for the future so he can hopefully be seen as a greater candidate. After his interview I just tried to warn him about saying too much about his future plans and he got super upset and took it as me saying that I am jealous of him. Which was not my intention at all. I guess my point is he gets so defensive easily and takes things so far. I told him I didn't mean any harm with what I said I was just trying to help him out. Kinda prior to this I was having a weird day and him yelling at me was overwhelming me so I decided to pack my bag and go home. He will go on an on about things when he is upset and it's so annoying. He saw that I was packing up and was like "where are you going" and I said I need to get away I just need a breather like you are doing the most. I also HATE to argue. So he says "I'll be fine without you anyways" and throws my shoes and coat out of the door. So I'm like okay whatever. I pack my things and walkout into the hallway. After I pick up my things and walk towards the stairs he grabs my backpack and pulls me in back into the room. Keep in mind, we are in a dorm he's doing this to me in a public hallway. He ends up pulling me in there and I tell him to get off of me this is not okay and I do end up getting out and he took my keys and wallet so even if I wanted to leave I couldn't so I sit out in the lobby on his floor and do homework because I am already pretty worked up and I'm trying not to cry. A few mins later he comes to me and takes my phone and book bag and says you don't need this and goes back to his room and goes on the "find my iPhone" ap_p and puts my laptop into "its lost" mode. so then I can't do my homework. It's just the petty, childish shit that I am tired of. He ended up apologizing to me but recently he has been pushing my buttons again. Yesterday we went to run some errands and I needed new sunscreen because the one that I was using kept leaving a white residue and he needed to go to the store for butter. After we got his butter from he store, we looked at the ingredients in the sunscreen that was leaving the white which was titanium something (I lowkey forgot). But I would try and find a brand without it (which is literally impossible lol) but he was getting mad at me like what is it to you omg. Later on when we where hanging out after shopping we where doing two separate things and he was on his phone laughing at something idk but he was laughing super loud like dude you live in a dorm be respectful yk so I just told him "hey keep it down" n he was like "make me" so I got up and left. I just needed space tbh like why is he acting like a child and can't take light criticism? Next day (today), I texted him this morning and no response. We so have each others locations and I saw he went to his first class and still didn't text me back. Like what are YOU mad for. What do you guys think? I tried communicating and we usually work though arguments but his actions are not changing in my opinion..
