Hello /bant/ i've got a problem. I just found out my gf likes anime.

I mean she's not a weeb, but she started sending me stupid gifs while chatting like pic related, and she asked me to watch stupid anime movies together.
The problem is, i made a promise to myself that i would never like or go out or even talk to people who like animes.
We've been together for 2 weeks.
She really loves me, and i know she'd feel so bad if i left her, for an apparently "stupid reason" like this one.
What should i do?

>inb4 nudes. I won't send her nudes, i'm loyal like a crusader knight.
