Can someone tell me what I need to do

So basically me and my boyfriend have been having issues. He ended up deciding that he would stay at his friends for a couple nights. (We live together) I used to be very passive aggressive/snappy and I’ve been working on myself over and over again. This week and last week I have finally done a really good job at handling my emotions. I would say I’m extremely healthy now. So one day I told him I would make him some nachos because he was hungry after I had already made a little bit of food for him. So the nachos get done and I start having some. (I did technically tell him I was going to make them for him.) So my sister wanted a few too even though I made her other food and she had some of his nachos. He ends up looking at me and goes “this was supposed too be my dinner” (I’m unsure of the tone of voice he used and I also already made him dinner but it turned out to barely be any food.) So hearing that was a little upsetting (I had cleaned all the plates and pots that was used to make the nachos) and I say “I thought I could have a few too.” He continues to say “no I’m talking about Your sister eating them” and then I respond saying “I feel like you wouldn’t say that about my sister” (keep in mind this is a very normal tone of voice and normally he wouldn’t even care if people ate some of the nachos) he then immediately starts going upstairs and storms off. I end up going upstairs and he’s crying and jumps on me to hug me laying down (im worried he’s emotionally manipulative) (he had been snapping at me for the past couple days even though he left for a friends for a few nights because I was snappy a couple weeks ago. He also almost broke up with me over it. I don’t understand how it’s fair to put someone in that place and snap at them. Keep in mind he has been snapping at me for the past couple days when I had done nothing at all to him.) immediately after all this goes down and I have a conversation with him it’s like he doesn’t want to just say “im sorry” without a “but this” and when I explain to him you are not allowed to treat me like this. He doesn’t just say “okay” or anything. It’s almost like he tries to explain why it’s okay and “I’m stressed” but he wouldn’t tolerate me if I did that to him.

can someone please explain what I need to do. This feels unhealthy and unfair. It doesn’t feel like I’m allowed to talk about my feelings/emotions without him freaking out.
