Overreacting? Being selfish? (A bit long)

So for the past two days my boyfriend has been acting a bit distant and hasn't really been talking to me much. Yesterday he told me he was in his thoughts trying to think of more ways to bring money in, (he pays all of the bills so I offered to help hoping he'd finally let me help. He said ok that will be fine). So this morning I asked him to grab our son because I couldn't put him back to bed, (I've been up with him all night because it was my night and I just wanted to rest in the morning). So he got up and took him downstairs and put him to bed. Then when I came down he didn't even acknowledge me so I went back upstairs. Then I texted him asking what I could do to make him feel better because when he doesn't talk to me it makes me feel like I'm the problem. So he came upstairs and told me that he's upset because for the last two days he has had to get up in the morning to put our son back to bed. When I say I lost my shit, I mean I blanked out because I just couldn't believe he would even try me like that! Our son is 4 months old, for the first two months of his life it has only been me waking up during the night to get him and put him back to bed. After the first to months I sat down with my boyfriend and told him that he needs to help out now so we picked days where he gets up then I get up. After that for the next 2 and a half weeks, I had 4 days a week and he had 3 days a week of getting up during the night to get our son. And even during his nights he would still ask me to get up and get our son and I did it with no fucking problem. So eventually I told him there is no reason I should be working, going to school full time, and being a full time mom and you still have less days then me, so how about we split Fridays and that way it would be even. He said no. So for three months it was mainly me being with our son (I also wasn't working at first because of maternity leave so I was with our son all day too). Well after a while I put my foot down and said we're splitting Fridays & that's it. So today when he said he was mad about putting our son down two times I just couldn't believe it. As a mother working 30 hours in a hospital, going to school full time and taking care of our son full time while he works demanding hours, I have not once complained! I got up and did wtf I had to for the sake of his energy and happiness! And now he has the nerve to tell me I just don't get it and I'm being one sided. Like I am so pissed rn that I just want to break up with him and move out.
