Relationship struggles

When things don’t add up in my head I can’t seem to let them go. No matter how hard I try to forget I just can’t. My boyfriend and I had a disagreement the other day and I can’t se to get it out my mind. I understand where I messed up and acknowledged that but my bf seems that his only problem was me. This is what happened. I was at home and waiting for my bf to open up my garage. I was waving him down but he didn’t notice for a min. When he finally drove up the driveway I stopped him and said “why you got me looking crazy waving all crazy at you to open the garage and what took so long and why you wasn’t paying attention”. He said all he did was look up then look down and that was it. I was like “ok whatever” and left. Not thinking it was a big deal or anything, I walked in the house to my bedroom and got in bed. My bf walks in the bedroom a few seconds behind me and seemed off but I didn’t ask. He went to the bathroom. After I finish greeting our dogs I decide to wash my hands. When I got the the bathroom door it was locked so I unlocked it. It took me a sec to unlock it so my bf finished unlocking it from the inside and then I opened it. Washed my hands and when I left I began to lock the door back. When I locked it and was beginning to close the door back my bf said to me very hastily “what you locking the door for?” And I told him that it was already locked and I was just locking it back. He didn’t like what I said got and then responded with it wasn’t locked cause he didn’t remember locking it and I reiterated that it definitely was locked and reminded him that he helped me unlock it. As I’m closing the door and walking away he responds and say “man I’m not in the mood for your attitude rn”. I just ignored it and got back in bed. Up until then ABSOLUTELY NOTHING was wrong with me. It seemed as if he was projecting his feelings from another situation and telling me I was feeling some type of way when I wasn’t. Then after a few seconds after I had already left the bathroom he said again “man I still don’t even remember locking the door”, no he wasn’t talking to me but I responded and said “yes it was locked”. & that was when he had enough. He told me he felt like I shouldn’t have responded to him while he was talking out loud to himself in the bathroom. He told me that when I walked away from the car when you was tryna talk to me made him upset, which explained why I thought he seemed bothered when he came in the bedroom. I should’ve asked how he was feeling if I noticed, regardless of how I felt about the situation. But he did not recognize nor acknowledge that he was bothered by something and then something else happened and he got super angry for no reason. Cause now it seems that I’m the one who started stuff when it was you who was reacting based off of your feelings. Letting all these things build up and then exploding on me. I can’t continue to be the only one who makes mistakes, reacts before I think about something, or just explodes on you and then acknowledge and apologize for it and MEAN IT. Yes, after I told him that it was locked the first time, his initial response was “I don’t remember locking it but my bad” but right after that he got angry with me and responded that he wasn’t in the mood for my attitude which didn’t make any sense cause I wasn’t angry or anything. It felt like he was angry and wasn’t projecting his feelings properly and when I brought that to his attention he just kept telling me how all of this was my fault cause I responded to things I shouldn’t have. Not how I responded. Not what I responded with. Just what I responded to.
