Why is my girlfriend like this?

Hi! I have a girlfriend and we have a sexual relationship.

Last week, I got into a real brutal fight with her one and only long time best friend who is male. He brutally beat me up in the fight in front of her which left my face suffering bone fractures. The fight happened due to him hating me and I don't know why. I feel like there is no reason. He's so strange. They were best friends before I met her. They are the same age while I am 3 years older than her.

Due to his gym habits, her best friend is muscular with six-pack-abs and big biceps and he is also physically stronger than most people his age such as when it comes to lifting, pulling, pushing, etc. He is also physically robust and strong due to constant manual labor. Also, he is a high-level hardcore MMA fighter while my girlfriend is a hardcore MMA fan.

But here's the weird part about my girlfriend.

After he brutally beat me up, she often hero-worships his MMA fighter identity in front of me, brags to me how amazing of a warrior he is, and how stronger and braver and more fearless he is than me. When I politely disagree neutrally and try to offer a logical explanation why, she often trash talks me about how her male best friend will destroy me easily like how rival NFL fans trash talk each other.

He is literally her idol and she thinks that he is the strongest, most badass person she ever met personally or knows in close proximity.

In front of me and after he brutally beat me up for no reason, she often hero-worships him(like how an overly enthusiastic little boy fans over his favorite male superhero) by saying to me that he has the face of a strong mythical brave legendary heroic young warrior chivalrous knight champion male. She was talking about his facial structures and his face's physical appearance when she said that. She wasn't referring to his personality or skills when she said that.

Honestly, she already hero-worships him these ways before I even met her but doing it after he brutally beat me up? Strange.

Seriously, what the **** is happening and why is she acting like this to me?

Also, she said this to me:

“Babe, you are my boyfriend but my idol hero and warrior demigod is him.”

And then I was like “What the ****?”.
