Broken or fixable relationship

My boyfriend of 4 years and I have been in a rough spot in our relationship since a little after our daughter (9months) was born , we argue a lot but we get better for a while then back to arguments

I love him and our little family , I want to make it work

I feel like it's a lot of one sided arguments , I know I have things to work on and that it's not just him but he on the other hand feels like I am the sole reason for our disagreements.

When we argue there's a lot of "I don't love you anymore" & " If _ again it's over" from him .

Most of the reasons we argue are based on the fact he feels I don't have respect for him

One of our more recent argument was

We had a blowout argument about not letting him sleep enough , he works a hard job (electrician) but on most days works an average of 5 hours , when he gets home I let him rest and every now and then he will ask to nap when he does I will normally let him sleep 2-4 hours , when I wake him up to help with our daughter he complains that I don't let him sleep enough , he clams that because he comes from a big family ( in height and body size) he need to sleep a lot he says that he wishes that I respected the fact he works hard to make money for us and would let him sleep till he decided to wake up on his own.

Although he says he makes money for us he is very greedy when it comes to me wanting random things most of the time food ( I asked for chips that were 50 cents and he refused to get them and said the " if I was hungry that he would buy me actual food " when I asked later for food he said that I needed to stop asking for food , he a few days later bought me a soda at a amusement park right before we left that was 5 dollars (pricey but not for amusement parks) he said everyone was getting drinks from a gas station near by afterwards and that they had said that out loud I told him that I hadn't heard them say that ( which was true ) he then later said that there was no way I didn't hear them and the he was "deeply disappointed" in the fact he had to buy me a 5 dollar soda .

I feel like we argue about little dumb things and that we have growing to do , any advice is appreciate
