Am I the asshole for choosing to keep having a valorant porn addiction and abandoning my girlfriend?

I (22M) used to have a girlfriend (20F), we've been dating for 2 years now and the relationship was going smooth and I was planning to marry her. She's the kind of woman who would always have time to play with me, which I love. My favorite game was valorant, she decided to abandon other games just to be my pocket sage. But one day we were just normally playing some competitive, and when the round started I heard one of viper's voiceline which she said "come". I started to feel my dick rising and getting hard because of that, my girlfriend saw my super hard ass boner and thought she caused it. She insists on going afk just to have sex with me to get rid of my boner, but I was really horny about the viper voiceline and wanted some more and kept continued playing. My penis kept getting harder and harder whenever viper said a voice line, and my girlfriend started to get concerned. The match ended, and I just noticed that my shorts got ripped off because of my massive boner that a valorant agent just caused. My girlfriend was really in the mood for sex so I decided to finally do whatever she wants me to do. We layed on the bed and she started playing some romantic sexy music, but it didn't turn me on a bit. So I played "VALORANT viper's voicelines" on YouTube and kept it on repeat, my boner suddenly came back. When I was banging her she started to get annoyed of the background video of vipers voiceline.So she turned it off, and I suddenly got pissed off. I didn't feel horny anymore when viper's voicelines stopped playing so I stopped banging her and just decided to masturbate to Sova instead and it worked, his sexy Russian voice turns me on so much that my penis bursted a stack of thick and sticky cum. Our relationship started going downhill because of me getting addicted to valorant agent porn. We didn't talk for long because of that scene. One month later, she decided to finally visit me on my house and she walked into my room. She saw me jacking off to killjoy porn and her face expression looks like she was disgusted with me. She yelled, "IS THAT WHAT YOU WERE DOING FOR THE WHOLE MONTH?" We had a really heated argument, and I eventually gave up because I didn't want my parents to scold me. We kept having a relationship even though it's very toxic. And 2 months later we decided to have sex but I didn't get turned on by her once. I said,"You should cosplay as Reyna that'll make my dick bigger." She cried, she had enough with my bullshit. She finally said, "What do you choose? Me or your valorant porn?" It was a really hard decision and I eventually said, "I choose valorant porn." She quickly got out of my house and blocked me in every social media because she didn't wanna contact me ever again. Valorant dicks and pussies was the only thing that kept me happy, and I didn't wanna lose that
