My (29F) husband (31M) has waifus.

I've never been more humiliated in my life. I met my husband (31M) when I (29F) was 20. We had a whirlwind romance, got married at 22 and we've been together for 9 years now. He is a good husband, puts food on the table, takes care of our baby and is generally a decent person to have a conversation with. I've felt generally happy in our marriage until yesterday. Before I met him, I knew he was a nerd. I'm not really into that stuff, but that's okay. You can't have it all, and I'd take a good, sweet, decent man over a bad one any day. <br><br>Yesterday I was looking for a TV show to watch, and I opened his phone to look at his recommendations. I use my phone for most of my TV watching, so I logged into our shared account on his phone. After a few minutes of scrolling, I noticed his watch history. On the front page were a bunch of dozen hentai clips of some anime I've never heard of. I pressed on it and it showed me all the available clips, and the computer recommended ones based on what he'd already watched. Suffice it to say that it was sexual and fetishy in a way that I didn't expect my husband to be into. I immediately left the app and checked his web history. It was filled with links to those hentai and other similar NSFW stuff. There was one weird ass link that looked like a social media profile. I clicked on it, and it was a profile of an anime girl designed to be sexy and cute. The name was the name of the anime and it had words like "wife" "bride" and "young girl" in it. I clicked on the profile photo and it opened a page with links to pictures of the anime girl and a bunch of statistics like age, bust size, height and other details that I didn't pay attention to. I also noticed that there were multiple similar profiles on the page, but this one had the most activity. I downloaded the page to view it later, but it looks like most of the stuff is links to other sites with more pictures or fan art.<br><br>Now, I'm not stupid. I know that my husband might occasionally watch porn, but this kind of organized, fetishy, obsessive behavior makes me feel like a fool. I know that he has a 3D wife, but does he really need to cultivate a relationship with a 2D character? Does he really need to keep track of the dozens of other 2D girls in his life? What the actual fuck? What does he do with them? He spends hours with me and our child every day. Does he spend his late nights "hugging" his anime bride? The worst is that I don't know how to bring it up. I don't know what to tell him or how he'll react. Am I even justified in being upset? Is it that big of a deal? Do I even tell him that I saw his profiles or do I approach him about the content? I just don't know what to do. <br><br>&#x200B;<br><br>Edit: 1. I don't care what he watches, it's the relationship that's the problem. 2. He uses a shared TV account. That's why his porn history was on the TV.<br><br>Edit2: To the people in the comments defending his "right" to have an anime bride, please consider that a marriage is supposed to be between TWO consenting parties. Is his anime bride a consenting adult? Is she a human? Does she have her own thoughts and desires? If you try to defend it, you'd be better off saying that he has a doll or a fleshlight. At least they are inanimate objects. This is literally a form of delusion.
