Is it porn or is he cheating? Update

I was looking through my hubbys bank statements like I do every month to tally up how much we’ve spent and what we can cut back on. What is usually a quick and easy task took me longer and completely shifted my mood this time because something caught my eye as I was looking through it, I found this strange transaction. Now, the whole porn thing doesn’t bug me, what does is when I see him spending our already tight budget on porn. I’ve tried looking up the name but all I found was PornHub girl with a similar name. What I can’t understand is if it were a transaction directly from Pornhub, it’d say so, wouldn’t it? It also charged him an international fee aside from this one. I’m hoping it was just him being a horny idiot and buying porn so I can calm my nerves.

I don’t want to go in directly accusing him before finding out where the transaction was from. Any ideas??

UPDATE: I was dreading having to ask him because I was afraid he’d lie to my face and I didn’t want this to turn into a huge fight. I called him into our room this morning, casually asked if he had been purchasing content from cam girls. Without taking a breath he denied it. Feeling irritated, I asked him a second time and I told him to think about what was going to come out of his mouth first before responding. He let out a nervous chuckle and admitted he had purchased photos/videos from an Instagram girl. He said he felt stupid for doing it and wasn’t sure why he went through with it. The thought of him sending money to a girl in exchange for a few pics/videos feels a little too insulting considering he has plenty of photos and videos of me and there’s literally free porn everywhere! Not to mention, what a waste of money it is. I let him know straight and simple that if that was what he was spending our money on, I would be through sharing my income. I’m okay with the whole porn thing, but purchasing personal pictures and videos from a girl, especially an Instagram amateur is disrespectful as fuck and I won’t be putting up with that. He apologized and reassured me it wouldn’t happen again. I’ll be paying closer attention to our bank statements but I really hope it won’t be a reoccurring thing.

Thank you for everyone’s response!
