What would you guys do? Need advice please

Me and my boyfriend have two kids together and I’m starting to question if this is something every couple deals with. My boyfriend is perfect on paper, he had a job, is a hard worker, he helps with the kids and house. I’m thankful for those qualities in him and he knows it. But, his flaws are addictive behavior, over spending, he calls me names when we fight (the b word, stupid, idiot, crazy) he tells me I’ve ruined his life. I am usually always the one reaching out after a fight or argument. I totally understand the cooling off process for a guy but it starts to get to me when he ignores me for a couple days. We have a joint bills account, anyways I told him that we will only have 5$ until payday with all out bills coming out in the beginning of the month and I have a couple more bills that I have to pay. I communicated that and he agreed and understood, so I thought. Promised he wouldn’t spend any more money. Anyways I check the account to make sure we are going to be overdrawn and i saw that he spend 75$ after I explained to him how tight it was going to be. I called and found out what happened and he said I should be proud of him because he didn’t buy what all of his other buddies bought and he feels lame that he couldn’t. I told him that we’re on a budget and he made me feel guilty for being upset. He ignored me all night and so far all day today. Am I being unreasonable? I’m a saver and he is the exact opposite and we’ve talked finances before and he always says he’ll stop spending so much money but NEVER does. Any advice? I feel like everything I say goes unheard and he just tells me what I want to hear to shut me up. I feel like he’s always on edge and snaps at me a lot. He never gives me compliments other than I’m pretty. Everything has been feeling so forced lately. Anyways I’ll stop ranting. Thank you in advance.
