Am I wrong?

I just made a new profile so there isn’t back post to go through and get some more info, gonna try and recap the best I can for you. Boyfriend is in his 40s with 5 kids from a previous marriage. I’m in my 20s and have 1 son. I met my boyfriend summer of 2017 and had my son spring of 2018 y’all can do the math on that. Boyfriend has always worked 50+ hours a week, iv stayed home with my son or worked 10 hours a week or what ever boyfriend has always been the main bread winner for both households. Him and his ex wife split everything 50/50 with the kids. Like a year after having my son my boyfriend asked if I could keep track of the bills, he’ll transfer a set amount into my account each week and I just make sure everything is paid on time. So for the past 4 years iv kept track of all of the bills, when automatic pays are going through, when we pay his mom for babysitting, how much of each check should go to rent, if it’s a kid birthday which week can we cut back on bills to do something with the kids, I plan family vacation all of it. Which is fine but it’s a lot of mental gymnastics some days. I do work full time now, my checks mainly contribute to household things and grocery’s and my son. Boyfriends checks mainly cover the bills not that there is no crossover but that’s how it’s always seemed to work. So a couple weeks ago my brakes just died on me. I had to pull what I had already taken for the rent and all of my savings to get them fixed. I write down all the bills like a month a head since boyfriend and I both get paid weekly like we get paid on the 18th and the car payment is do on the 22nd I gotta hold money from the 18th to make that payment. So Iv had to redo March’s budget cuz I gotta put that rent money back. I’d like to put my savings back. We got 2 birthdays this month plus our anniversary so Im not trying to go to bill heavy every week but like 80% of our bills are automatic so the money has to be in my account. So I’ll type out the fight in a second but just for information we just updated my phone so I knew the phone bills was gonna be more this month but that’s not really what happened also the phone bill comes out automatically on my boyfriends account on the 16th of the month. So I’m at work running errands for my boss which is awesome it’s drive around and drink Starbucks and listen to music while getting paid and my boyfriend calls. I’d also like to add that there is like next to no money in my account and I’m holding onto two automatic payment money and then a check my mom had given me that I was gonna use to order the stuff off Amazon for our granddaughters first birthday.

Boyfriend: “I need you to send me $120”

Me: “why?”

Boyfriend: “the phone bill went through”

Me: “what do you mean it doesn’t through till the 16th and it’s normally like 250, so why 120 now, are we still gonna have to owe 250 on the 16th”

Boyfriend: “I don’t know why you got an attitude it’s like you don’t believe me or something.”

*sends me a screenshot of his transactions”

Me: “it’s not that I don’t believe you, it just never comes out at this time it’s weird and frustrating cuz I just redid the bills and now I’m gonna have to do them again.”

Boyfriend: “I don’t even know why I called you, you always have an attitude I’ll just borrow it from my brother.”

Me: “that doesn’t really fix the problem because then we will just have to pay your brother later. I’m pulling into the parking lot right now let me double check the check from my mom cleared cuz I won’t even have it if it didn’t”

Boyfriend: “fix your face” (we’re in FaceTime)

Me: “stop talking about my face we know I have RBF you bring it up everyday, like I’m at work, I’m driving, I don’t even know if the check cleared, why is the phone bills coming out early, like I’m frustrated not gonna paint a smile on my face right now I’m allowed to be frustrated.

At this point iv gotten to my destination and checked my account and the check had cleared so I sent him the 120

Me: “ok I sent it but can you please call the phone company today and figure out what’s going on.

*sends him a screen shot of the spreadsheet of bills I have* like I’m gonna have to redo this now and literally just redid this for the brakes. Like it’s frustrating sorry my face shows it”

Boyfriend: “no I’m not dealing with this I’ll ask my brother”

*sends the money back*

Me: “why would you send it back. Omg never mind I have to go but I don’t want to hear later that you can’t send me the bill money or this or that cuz you owe your brother now. Like makes no sense.”

At which point my boyfriend hung up texted me that I was his wife and who else was he gonna call but what ever and like in that same note then he’s my husband who else am I gonna be annoyed at the phone company with also also we’re not married.

I Just replied with “don’t bother me I’m at work” which is his response anytime I call him with a problem and he’s at work. And we haven’t spoke since.

I just hate this always having to be happy like no I’m annoyed and frustrated why can’t I show it. Am I wrong?
