What do you guys think?

So, for various reasons me and my husband have different bank accounts. He makes much much more than I do, so I just pay whatever bills I have the money for. I normally do not have hardly any money left for myself though.

Well, we've been having a lot of problems lately because of his excessive drinking and have been fighting a lot. My best friend wanted to take me to this nice store that's pretty much a grocery store for snacks to cheer me up. This was a couple nights after me and him had a big fight. When I told him I was going to go snack shopping he told me to take his card. I let him know I was planning on splurging because this place is fairly far away and theres alot of stuff I'd like to try and he said it was fine.

Well when I got there, there was wayyy more stuff that I wanted to get than I thought. I knew if I was using my money I wouldn't be able to get much, but he had a good amount left after bills, so I figured I could get some extra stuff. So I called him for a couple of the things I wanted to make sure it was okay, since some of them were fairly pricey, and after like the 4th time I called he told me to not worry about it, I don't need to call him to ask, just get whatever I want and that it's his way of apologizing for being so mean to me lately. So I did exactly that and got everything I really wanted. For the record it wasn't actually a ton of stuff, it's just that most stuff there is pricey. When I got home and he asked how much I spent, I told him about $250 and he flipped out on me, saying that he didn't mean I could go that crazy and if I was planning on spending that much I should of told him. I didn't know it was going to be that much until I checked out though, it was only a few bags of stuff, its just everything is expensive there. I told him sorry but I did tell him I was splurging and called him about the more expensive items ($40 cake, $15 jar of jam, $25 cheese), and that he spends way more than that on his booze each week anyways, but now hes pissed at me. I talked to some of my friends about it and they said I shouldn't of spent so much just because it was his money and not mine, but he said to get what I want. AITA here?

Edit: since it's been mentioned a lot and I was asked to add it to the post, it wasn't what people normally consider snacks. I got stuff like vegetables (pearl onions, small colored potatoes, etc), some exotic fruits, spices and fresh herbs to cook with, a nice bag of coffee beans, and other non essential groceries to make meals or snacks with.
