My [24f] BF [25m] is obsessed with a fictional character, I can't deal any more

I hate myself right now. I technically started this because I invited him to join me when I started watching a TV series a few weeks ago.
After a couple episodes he began commenting on how attractive the character was (she is dressed somewhat revealingly throughout the series) a few more after that and the train to Crazytown had left the station.
Since then, EVERYTHING revolves around this character. Here's some examples of what he's like now:

• Blown off work pretending to be sick, so he can sit at home rewatching scene's she's in
  
• Downloaded every single episode of the show.
  
• Finds ways to bring her up in conversation whatever we are talking about, I mention something someone did and he'll say "Hehehe that sounds like Character!"
  
• He points out insignifigant things and connects them to her, like if a woman has hair like hers
  
• Looked up Cosplay for me to wear even though I'm not interested in cosplaying.
  
• More specifically, wants me to dress in it and role-play her in bed with him, I told him NO, he got upset. He's begged me 3 times to do this.
  
• Stays up til sunrise some nights on the internet watching clips of her scenes or browsing fan art and rule34 photomanips people made, then oversleeps and misses work (Side note, it's a very small fandom so there's not a lot of content out there, so he's downloaded and saved it ALL. I saw it organized in folders on his desktop that I use sometimes. Also the background on that and his phone are images of her, of course.)
  
• Related, I get to hear regular complaints about how there isn't enough pictures and fanfiction involving her
  
• Lamented that there's no VR porn of this character (??? I guess there is VR porn of OTHER characters?)
  
• She's the "sexiest Goddess" in his words. What the ****, who says that to their GF?? He's told me in detail the things he wants her to do to him sexually......
  
• ****ing called me by her name in bed, twice. Since this started we've gone from sex a few times a week, to once at the most and he won't admit to what I suspect is frequent masturbating in the bathroom
  
• One night I woke up from him moving around and making noises in his sleep. Then he woke up and got out of bed. I asked if he was okay and he said he'd had a wet dream about her.
  
• All of this has killed my enjoyment in the show and now I can't finish it. I quit watching because everytime we watched became just him moaning everytime she was on screen over how hot she is, he didn't care about anything else. He just kept watching and finished the show without me.
  
• Most recently he showed me his project of editing all the scenes she's in through out the ENTIRE series, all seasons, into one complete montage. I'm sorry but that's crazy-territory, right? That is hours and hours of content and it's as if nothing makes him happier then rewatching it over and over again, hyper focused on this one person. Once he has that montage complete I don't even want to think how much time he will waste watching it.
  

I AM SO SICK OF HIS OBSESSION. I WISH I'D NEVER TOLD HIM ABOUT THIS SHOW. It's not even like he's interested in the actress or her other work which I could maybe get, celeb crushes happen. No he's interested in a FICTIONAL character. This woman doesn't even exist! It makes no sense!
Anyway it's been nearly two months now. I've told him soooo many times how it makes me feel ****ty like he's dump me in a heartbeat for this character if she was real. I don't want to hear how hot someone else is all the time. I don't wanna feel like I got to act as someone else for him to be attracted to me.
I feel trapped in some kind of timeloop where we keep having the same stupid conversations either him obsessing about her to me or me getting annoyed. No matter how many times we have this argument it goes the same way: he apologizes in what sounds like a sincere way, then within a day or two he keeps making these comments.
I've also told him my worry about him skipping work and his other behavior I listed like not sleeping. I grew up with a deadbeat alcoholic father, and I remember him losing job after job because he would skip work to get drunk or was too hungover to go in. My older brother is addicted to video gaming and does the same thing. My point to my boyfriend was that his obsession is getting to the "will **** up his life unless he gets control soon" level. He said I was being a drama queen and liking a character is nothing like being an alcoholic.
Nothing will get through to him.
We never do anything together anymore because of this, all he wants to do is be on the computer lost in this fantasyworld. We've been together for 3 years and moved in together recently. How can you live with your partner but feel like you barely ever spend any time with them.
Please help me to understand this?? Has anyone done this same thing or known someone who did? What helped them stop it? I am so over it and desperate for any suggestion. I desperately don't want to break up over something as ridiculous as a fictional character. The irrational part of my brain says I'm losing him to her. I wish he would just....care even a little how this is making me feel.
PS, sorry this turned into such a long emotional rant, I'm too embarassed to talk to anyone I know for advice.
tl;dr. My BF is completely obsessed with one of the main characters in a show I introduced him to. It's like there's nothing he thinks about any more except her. He's bailing on work, sleep, sex, anything together with me to do things online related to this character. Does not see any problem. Help.

Damn...OP wrote all of that...she just as crazy as her bf.

Seriously, are the these people really so inexperienced at life that they can handle a situation like this? I mean, she's 20 FRICKING 4 years old....with a 25 y/o bf obsessing over a fictional character. God what a bunch of gaping vaginas.
I'm HOPING that alot of threads like this are just troll threads....if we've become this stupid, we're in trouble.

@MrWalkSoftly: we ARE in trouble. Lol.
This is what society has devolved into, sadly.

@Roachvaliek: I'm afraid you're right.
I also just read about a California state politician who proposed a bill making it a criminal offense for a waiter or waitress to offer a customer a plastic drinking straw....environmental bullshlt...I'm about to get all for extending the wall 1500 more miles north considering some the absolute horseshlt coming out of CA lately...

Edited to add:

""Ian Calderon wants restaurateurs to think long and hard before giving you a straw.

Calderon, the Democratic majority leader in California's lower house, has introduced a bill to stop sit-down restaurants from offering customers straws with their beverages unless they specifically request one. Under Calderon's law, a waiter who serves a drink with an unrequested straw in it would face up to 6 months in jail and a fine of up to $1,000.""

@MrWalkSoftly: California wants to leave the union too.
I think they should. "Good riddance!", I say.
