My boyfriend thinks i’m too angry

Me and my boyfriend have been together for 8 months, and today he told me that he thinks i’ve been “too angry” our entire relationship. He said that I always scold him and get mad as soon as something happens. And that when we have money issues I get mad at him. The last part is true. Before I met my boyfriend I had no problem with saving money and being responsible with my money. I started dating him and instantly noticed that he was extremely bad with money, and this quickly became my problem. When his money ran out, it was then my budget that was blowing just because he couldn’t save a penny for the life of him. We’ve had lots of arguments about money and we still do. So yes, money is a big reason why i’m constantly stressed and mad. I have tried to help him save, set up a budget, apply for jobs etc but now I let him handle it himself. I get easily stressed and anxious about everything, and then I get mad because I feel like I handle everything by myself in our relationship. I feel like i’m the only adult and that i’m the only one being responsible and it’s stressing me out. I do lash out sometimes and scold him, and I mostly apologise, but it gets too much sometimes and I get overwhelmed by everything. I get all the responsibilities for everything we do because “i’m so good at it”. Now he’s mad at me because I sometimes scold him. It’s not like I get mad everyday, only in situations when I feel pressured and stressed and alone. I don’t know if i’m overreacting or what to tell him
